Fix various issues with room events and related logic. 

- Processing events multiple times when re-joining rooms.
 - Always thinking we've not processed an event/constraint
   violations (arguments were reversed in record_event).
 - Not handling errors when fetchin users in a room, and instead
   just suppressing them. Now, we handle errors!
 - Also update dependencies (attempt to fix ID too big bug, but no
   fix).
