[gtk/action-muxer-speedup: 9/12] inspector: Make the actions tab work again

commit 127bb69054b3a10dd4ae39cb875a4d5458197df4
Author: Matthias Clasen <mclasen redhat com>
Date:   Sun Jul 19 01:56:00 2020 -0400

    inspector: Make the actions tab work again
    
    Bring back the actions tab; we don't receive
    changes anymore, since GtkActionMuxer lost
    the GActionGroup signals for this, and the
    action observer machinery has no way to listen
    for all changes.
