saveKeysToDeviceObject is the detector of outgoing identity key errors.
Catch these key errors closer to the source by pulling the
getKeysForNumber into the context of sendMessageToDevices, which lets
it access registerError and the message protobuf.
Previously identity key errors would be uncaught if all existing
sessions with a recipient were closed/deleted, since we would
preemptively fetch the new identity key. The old error handling only
kicked in after a 409/410 response from the server when posting a
message encrypted for a stale session.

Previously we would convert a bytebuffer to a string, pass it to
libaxolotl where it would be parsed back into a bytebuffer.
Ideally we would just pass the bytebuffer, but it turns out that
libaxolotl's bytebyffer class is identical but separate from
libtextsecure's bytebuffer class. ¯\_(ツ)_/¯
So instead we pass the underlying array buffer, which is handled
more or less the same way as a bytebuffer, and most importantly,
does not involve any copying.

We now disconnect ourselves if we don't get the server's response to a
keepalive request within 30s. This way we will eventually disconnect if
the network goes away but the socket is not closed.*

https://stackoverflow.com/questions/11755605/chrome-websocket-connection-not-closed-when-browser-closed
We will then try to reconnect once a minute (See 8a10c96);
Keepalives belong at this level anyway, since the format is defined by
both the websocket resource protocol and our specific server url
structure.

This trigger function uses chrome's runtime message passing api, which
traverses between different windows in our runtime, but we only trigger
the updateInbox event from the backgroud page, so we don't need to use
that api, which requires some extra cpu/memory overhead.
// FREEBIE
Well that didn't work. Luckily this comparison is primarily enforced at
the libaxolotl level.
With this and the corresponding change to libaxolotl, remote identity
keys are always going to be stored as array buffers going forward. This
will cause incompatibility with existing keys stored as strings, so
updating to this point requires you to purge your identity key and
session store.
We're overriding the default with null often enough that we should
just change the default.
Consequently, no more phantom blank conversations with oneself should
appear after receiving a group update. They were being added to the
inbox because they were incorrectly initialized with an active_at value.
Fixes#281
All the old event listeners and in-memory objects have perished with the
old background page. Also reopen the inbox if it was already open.

The following are equivalent, except that the first is longer and
invokes an extra function call.
```
return new Promise(function(resolve, reject) {
reject(new Error("Unknown Group"));
});
return Promise.reject(new Error("Unknown Group"));
```
Refreshing the background page does re-open the socket, but the inbox
and other windows don't reattach correctly. Reload the whole runtime to
force close all windows, reload the background, and re open the inbox.
In lieu of a click event, the change event was being fired when clicking
out of the search input. The input event seems to be what we actually want.
Fixes#273
This bug was caused by a race between indexeddb requests and sending
messages. Order of events to repro was roughly:
1. send async idb request for current message list
2. add new message(s)
3. idb request returns with now incomplete message list
4. message collection gets reset to list from 3, removing messages
added in 2, but not removing their phantom views/dom elements. (bug)
5. send another idb request for current message list
6. idb request returns bearing all messages including those from 2.
7. messages from 2 are added and rendered a second time.
The fix was simply to not remove messages in 4, which means we reuse the
original message model object rather than recreating it in 7.

The unset function, and the series of events/callbacks triggered by its
use, are not as similar to the set/save functions as previously
anticipated, leading to flux in the state of the 'pending' attribute.
