Fixed
- [[216]] `AsyncClient.room_get_state_event()`: return a
`RoomGetStateEventError` if the server returns a 404 error for the request
- [[ffc4228]] When fetching the full list of room members, discard the members
we previously had that are absent from the full list
- [[c123e24]] `MatrixRoom.members_synced`: instead of depending on the
potentially outdated room summary member count, become `True` when the
full member list has been fetched for the room.
