Add indices. Remove room_ids accidentally added
We have to do this by re-inserting a background update and recreating
tables, as the tables only get created during a background update and
will later be deleted.

We also make sure that we remove any entries that should have been
removed but weren't due to a race that has been fixed in a previous
commit.
