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.
* unify single and multi contact selection activities
* follow android listview design recommendations more closely
* add contact photos to selection
* change indicator for push to be more obvious
* cache circle-cropped bitmaps
* dedupe numbers when contact has multiple of same phone number

The ACTION_GET_CONTENT used with cropping is not supported on all devices.
To make this work more reliably I removed the cropping and MediaStore.EXTRA_OUTPUT.
The image is now read via getContentResolver().openInputStream() which should work on all device including KitKat/CM11.
