This should help ensure that equivalent results are achieved between homeservers querying for the summary of a space. This implements modified MSC1772 rules, according to MSC2946. The different is that the origin_server_ts of the m.room.create event is not used as a tie-breaker since this might not be known if the homeserver is not part of the room.
