Emit Room Selected from JoinRoomPage

Change the `JoinRoomPage` so that it emits a `roomSelected` signal with the selected delegate's info instead of calling the functions to join or enter the room itself. This is so that the `JoinRoomPage` can be used for other purposes like selecting an existing child to add to a space.
