When we first hit the start of the room, we still have a pagination token, so
we hide the date separator. When we try to backpaginate again, we get an empty
result, and the pagination token is cleared.
Make sure that we update state. canBackPaginate even when there are no new
results, to handle this case.

If the event corresponding to the read-up-to mark hasn't been loaded into the
timeline window, we can't simply scroll to it. Instead, reload the timeline,
centered on the RM event.

This reverts commit a7c75b1315, reversing
changes made to b66ca74ede.
This is causing breakage in the messagepanel screen resize after video call and
room settings
We had a problem handling gappy syncs: resetting the timeline would trigger a
pagination request (which would return no results, because there are no events
at this point); this would make the pagination requests which are spawned when
we process the events in the sync get ignored - with the result that we get a
blank window.
The fix is to avoid the ScrollPanel when we are processing new live events and
tell the TimelineWindow to paginate itself directly.
After a resume from sleep, we don't want to start paginating through the whole
timeline. If we were in 'stuckAtBottom' mode before, treat a gappy sync
similarly to how we handle the 'scroll to bottom' knob, which is to reload the
timelinewindow starting from scratch.
Fixes https://github.com/vector-im/vector-web/issues/932, and will probably
also fix https://github.com/vector-im/vector-web/issues/943, though I haven't
tested it yet.
