* Import type
* Add test to cover an existing issue. roomCoroutineScope is not cancelled when the class is destroyed
* Cancel roomCoroutineScope when the class is destroyed
* Move `isOneToOne` to BaseRoom, we do not need a JoinedRoom for it.
* Let `roomInfoFlow` be implemented by RustBaseRoom.
It should fix a few issues where we rely on the room info to be live, and it was not the case on RustBaseRoom.
* Add more assertions.
The test would fail anyway if roomCoroutineScope was still active, but it's more explicit with these assertions.
