Patch for SYWEB-40 : isStateEvent is not being set correctly, and really shouldn't be a configurable arg in the first place. As a result of being undefined, the events.rooms[rid].members object was not being updated in some cases, which combined with the recents-filter bug (32808e41), caused federated rooms to not appear in the recents list.
