- `s/Server/OutputRoomEvent/` in `consumers` to accurately reflect what is being consumed.

The logic for notifying /sync requests is about to get really
complicated as we optimise when to wake up requests, so split
out that code into a separate struct to isolate it and make
it easier to unit test.
