    extensionPrefs: Schedule updates check on activate
    
    While gnome-shell will now check for extension updates, the checks
    are performed infrequently. Opening the Extensions app implies that
    the user's current focus is on extensions, so it is an appropriate
    time to schedule another updates check.
