Replace sdkReady with firstSyncPromise, add mx_last_room_id

Browse source 
- Create a promise that will serve as a lock to be blocked on by things that need to wait for the first sync before accessing state.
- Use this promise to block `view_room` calls until a sync has occured instead of just dropping them silently if the sync hasn't happened yet.
- Store the current room ID in a localStorage item `mx_last_room_id` when `view_room` fires. This persists the last viewed room ID so that it can be restored on refresh, browser quit. This replaces the previous logic which set the room following a sync based on the most recent unread room.
