    userTracker: Remove some roomData helpers
    
    getRoomContacts(), getRoomHandlers() and getRoomSignals() hide the
    nested maps in roomData, which helps making the code more readable.
    However wrapping the Map() API for roomData itself only hides that
    roomData is a map, which doesn't seem useful.
