* sytest: Make 'Inbound federation can backfill events' pass This breaks 'Outbound federation can backfill events' because now we are returning the right number of events, which the previous test was relying on. Previously, /messages was backfilling the membership event, causing the test to pass. Now we are no longer backfilling the membership event due to the change in this commit, causing the test to fail. The test should instead be returning the membership event locally from synacpis database, but it doesn't do it fast enough, resulting in a no-op /sync response with a next_batch=s0_0 which will never pick up the local membership event when it rolls in. The test does attempt to retry, but doesn't take the new next_batch=s1_0 resulting in it missing from the /messages response. * Linting
