Both pointer and last are fields that were removed when we changed the
protocol to use events like a year ago.
This conveniently allows us to stop exporting get_updates_params to
other modules.

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.

Note that this makes the event fire after the home view has messages
loaded all the way to current; previously it only waited for the first
batch of messages to load.
