* Fetch all conversations on startup of app, not on inbox load
A recent change to fetch conversations less didn't take into account all
that can happen in the app without the inbox loaded. That only happens
when the window is shown, and messages can come in with the app in the
background. In that case, the conversation wouldn't have been loaded
from the database, but would be saved to the database anyway, losing
data.
This change fetches all conversations as soon as the the data store is
ready for a fetch. It also introduces failsafe throws to ensure that
synchronous ConversationController accesses don't happen until the
initial fetch is complete. A new getUnsafe() method was required to
account for some of the model setup that happens during that initial
conversation fetch.

* Fix tests: ConversationController.load() required before get()

Refactor libphonenumber.validateNumber into libphonenumber.parseNumber,
which encapsulates the try-catch pattern used in number parsing and
returns an object of info about the input number rather tha throwing
since we expect to get some invalid number inputs the user is typing.
In the conversation model,
* Separate phone number validation from search token updating.
* Perform token update before save if the number was valid.
* Stop storing unneeded number variants as conversation properties.

After a message is saved asynchronsly, fire an event and pass the
message attributes to frontend listeners via the chrome-runtime API.
This behavior is similar to the 'storage' event fired by localStorage.
Getting up and running with IndexedDB was pretty easy, thanks to
backbone. The tricky part was making reads and writes asynchronous.
In that process I did some refactoring on Whisper.Threads, which
has been renamed Conversations for consistency with the view names.
This change also adds the unlimitedStorage permission.
