Fix the missing date separator at the start of rooms

Browse source 
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.
