Florian Müllner 9e00e8a0fb 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.
