Room list service (#1138)

* Adopt the new RoomListService

* Use client.roomListWithEncryption

* Store the roomList so that it doesn't get dropped and create problems on the rust side

* Use roomListService instead of old roomList client method

* Added back documentation removed by mistake

* Tweaks following code review, SDK bump
