[nautilus/wip/coreyberla/app-chooser-fixes: 4/6] app-chooser: Only switch defaults if the user actually initiated a change

[Corey Berla <coreyberla src gnome org>]

commit 1b8228fdce3e0819ddedcd97194b26ffd6ef8f3b

    app-chooser: Only switch defaults if the user actually initiated a change
    
    The app chooser resets the default simply dependent on whether the
    GtkSwitch is active or inactive.  We need to check whether the user
    actually initiated that change, so store a boolean default_changed
    that toggles based on the set-state signal from the switch.
