* Factor out functions for injecting events into database I want to add some more flexibility to the tools for injecting events into the database, and I don't want to clutter up HomeserverTestCase with them, so let's factor them out to a new file. * Rework TestReplicationDataHandler This wasn't very easy to work with: the mock wrapping was largely superfluous, and it's useful to be able to inspect the received rows, and clear out the received list. * Fix AssertionErrors being thrown by EventsStream Part of the problem was that there was an off-by-one error in the assertion, but also the limit logic was too simple. Fix it all up and add some tests.
