Fixes#926.
We have to do this, since with the new Storage Access Framework,
otherwise we can open the Uri only *once*. This would work well
unless someone saves a draft and goes back to the conversation -
then the Uri is opened again without the required permissions.
See:
https://developer.android.com/guide/topics/providers/document-provider.html#client
...for details.
Currently the order of numbers is times contacted -> displayName ->
phone type (mobile vs. home, etc.). This adds whether the number has
been saved as the default number for a contact to sort numbers belonging
to the same contact.
Fixes#580
The current activity needs to be finished before calling startActivity.
Otherwise, activities with launchMode singleTask (ConversationListActivity)
will receive a new Intent instead of getting restarted. And in response
to the new Intent, they will run onResume once again and trigger a second restart.
Fixes#1292
1) Updating a group without changing the avatar will keep that
avatar
2) Prohibit adding non-push users to an existing push group
3) Add Android contacts to the same database. Takes a small amount
more time and memory, but allows queries to not be a hack, and
enables us to dedupe numbers in JB and higher devices.

1) Modify SessionRecord to store a list of "previous" sessions
in addition to the current active session. Previous sessions
can be used for receiving messages, but not for sending
messages.
2) When a possible "simultaneous initiate" is detected, push the
current session onto the "previous session" stack instead of
clearing it and starting over.
3) Additionally, mark the new session created on a received
possible "simultaneous initiate" as stale for sending. The
next outgoing message would trigger a full prekey refresh.
4) Work to do: outgoing messages on the SMS transport should
probably not use the existing session if it's marked stale
for sending. These messages need to fail and notify the user,
similar to how we'll handle SMS fallback to push users before
a prekey session is created.
