Perform preference schema upgrades at startup (#3186)
* Perform preference schema upgrades at startup

Over time it can be desirable to change how preferences are interpreted.

Preferences might be removed, or renamed. Or the default value for a
preference might be changed.

When this happens it's important that users upgrading from one version to
the next (or jumping from one version to several versions ahead) get a
consistent experience. In particular:

- Preferences that no longer exist should be deleted
- Preferences that have been renamed should have the old preference values
  copied over
- If the user used the default value for the preference, and the default has
  changed, the previous default value should be explicitly set as their
  value for the preference

To support this, store a SCHEMA_VERSION as a preference. This is not exposed
to the user, and corresponds to the app's VERSION_CODE.

If the version code does not match the schema version then this is a newer
version of the app with older preferences that may need to be changed.

Those changes will be implemented in `upgradeSharedPreferences`.
