Fix up array buffer comparison

Browse source 
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.
