[gnome-shell] messageTray: Don't create notification policy on demand

    messageTray: Don't create notification policy on demand
    
    This was changed in commit 8f15193b4 as a work-around for an ES6
    class limitation, but now that Sources are GObject subclasses, we
    no longer need to use that somewhat surprising pattern.
