Due to server bugs or whatever it sometimes
happens that old state events appear
in the setState method in the room class.
Previously we checked if we already know
this event ID, but for this we needed to
check the timeline which is very fluid.
Also this is a database operation in a
non-async method which works in Hive but
not in Sembast.
Using originServerTs is not 100% safe as
well but should be more stable because
the chance that servers have veeery wrong
time (which is necessary here) is much
lower than the risk that the timeline
is not long enough to know the
old event.
Previously we had a check which uses the old
sortOrder value.
This check has been removed with the refactoring which leads to
bug #209. This fixes it by checking if the
event is already known in the database.
I am not 100% happy with this solution as this database api is impossible
to be implemented with a sqlite db. Once we start to refactor the whole sync update logic
we maybe could find a better way, but only the fox god knows.
RoomUpdate came from a time where we had no data model for
SyncUpdates but now we have and therefore this class is just
code duplication. This removes the class
and uses the SyncRoomUpdate class from
the package matrix_api_lite instead.
It needed a lot of refactoring at some places
where I also have removed some unnecessary null or type checks.
