The Logging in integration tests is problematic

[Gnuxie]

1. We have far too many irrelevant calls to LogService.error from the matrix-bot-sdk MatrixClient for things that are expected ie getting a 404 when checking for the existence of a room alias or querying state events. This is causing a sort of alarm fatigue and makes it harder to look for the causes of problems in a full run (yarn test:integration).

2. Mocha writes to the output stream in a completely inconsistent order to LogService. it can make the logs from MatrixClient or other components appear as though they are a result of a calls from a different test than what Mocha says has failed or has started running. Not sure if this is something from Mocha not awaiting test callbacks or something else.
