Load JoinedRoom in home screen, pass it to the room flow (#5817)

Browse source 
* Load `JoinedRoom` in `HomeFlowNode.navigateToRoom`, then pass it to the next navigation nodes

* Add delayed loading indicator for cases when loading the room takes too long

* Avoid an extra FFI call in `RustRoomFactory`.

Use `RoomInfo.membership` instead.

Also use `computation` dispatcher, since it should reduce the delay when switching contexts.

* Remove the dispatcher usage when loading the room in `HomeFlowNode`, we immediately call a method that changes the dispatcher used

* Make sure only a single room is opened at a time
