Add some logging/recovery for lost rooms 

Zero inserts is not normal, so we apply the same recovery technique from the categorization logic above this block: insert it to be the very first room and hope that someone complains that the room is ordered incorrectly.

There's some additional logging to try and identify what went wrong because it should definitely be inserted. The `!== 1` check is not supposed to be called, ever.

Logging for https://github.com/vector-im/riot-web/issues/11303
