Start running get_events immediately on page load. 

Previously, we waited until we'd fully loaded the home view to start
calling get_events, which:
(A) didn't make sense non-message related events
(B) resulted in our throwing "get_updates not started" errors when
users sent a message before the home view was fully loaded.

This commit only fixes problem (B); to fix problem (A) we will need to
change the event capture code to only capture some events.
