Made users count auto updating. Do show it if the info is not available (ex:user has not joined the room yet)

Removed wrong comments about recents-controller.js: it uses $rootScope.rooms not $rootScope.events.rooms managed by event-handler-service.js and used by other controllers

Reenabled handle of room states events in initialSync but do not add them to the displayed messages in the room page.
Show the m.room.member events only when they come from room.messages (from initialSync of pagination) not from room.state.

Fix bug where we used an unbound local variable if we ended up rolling back the persist_event transaction

Killed an unexpected pagination trigger when the page load: paginateMore

Do this by synchronizing the m.room.member joined event from the events stream and the start of the pagination
