[gnome-software] Add a signal for 'refreshed' to GsShellOverview

[Matthias Clasen <matthiasc src gnome org>]

commit 628b597fd92b1a5a94d6ad247c8a48c50fd2c36c

    Add a signal for 'refreshed' to GsShellOverview
    
    This will let us avoid slowing down the loading of the overview
    by deferring the load of the other tabs until the overview is
    fully loaded.
