Summary:
This diff adds persistent unique ids for messages and contacts. For messages, we just take a hash of the headers. For contacts, we hash the contact's email address.
This diff bundles a couple of tiny fixes too, like always trying to restart an account's sync, even after an exception.
Note that since there's no reliable way to have persistent ids for threads, we'll have to change our code to use message ids instead. Alas, that's a story for another (massive) diff.
Test Plan: Tested manually.

This will only generate 1 delta per new message instead of 2
Adds a MessageFactory to create messages from imapmessage objects, and
unifies and cleans up that logic
Also modified the message-processor to be more suited for local sync,
made emphasis that it's only for processing new messages, and got rid of
the while "pipeline" concept
- TODO message-processor specs are broken
