group and contact list fixes

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.

Before this change opening the drawer while a filter was active would hide the
search bar but keep the conversation list filtered, so there was no indication
of an active filter.
