Replace client side room awaiting with the SDKs new awaitRoomRemoteEcho method

[stefanceriu]

Partially fixes #3256 where the join room screen doesn't have details about an invited room because the sync loop hasn't run yet (the preview api can't help here either because previews are disabled). Also fixes edgecases in which the room summary was available but the room not fully synced when used for creating/joining rooms.

• the part about the push notification not having content seems to be related to a missing event_id field between SS and SSS

Requires matrix-org/matrix-rust-sdk#3979

LGTM 👏

Is there another place where we do this? Maybe the whole can init timeline thing? Or would that not work?
