[Matthias Clasen <matthiasc src gnome org>]

commit 0e0fe278e78eb8877f5798c01eee94b48d52cb7e
Author: Kalev Lember <kalevlember gmail com>

    Update the last installed timestamp after successful offline updates
    
    This makes sure our internal timestamp is up to date after an external
    app (e.g. gnome-shell) has triggered offline updates.
