syncapi: add more tests; fix more bugs (#2338)

Browse source 
* syncapi: add more tests; fix more bugs

bugfixes:
 - The postgres impl of TopologyTable.SelectEventIDsInRange did not use the provided txn
 - The postgres impl of EventsTable.SelectEvents did not preserve the ordering of the input event IDs in the output events slice
 - The sqlite impl of EventsTable.SelectEvents did not use a bulk `IN ($1)` query.

Added tests:
 - `TestGetEventsInRangeWithTopologyToken`
 - `TestOutputRoomEventsTable`
 - `TestTopologyTable`

* -p 1 for now
