[gnome-disk-utility/gnome-3-8] Make dialog work with --xid again

[Matthias Clasen <matthiasc src gnome org>]

commit 76f5e0e98a86e5a91f636ae2fb74c5b6663208ab
Author: Matthias Clasen <mclasen redhat com>
Date:   Wed Jan 8 19:25:03 2014 -0500

    Make dialog work with --xid again
    
    When triggering an async operation from a GApplicationCommandline,
    we must use g_application_hold/release to ensure the application
    instance stays around until the operation is done.
