    actor: Hide children before ourselves
    
    Fixes errors like:
    Gtk-WARNING **: GtkClutterEmbed 0x11a3300 is mapped but visible child GtkClutterOffscreen 0x15d0490 is not mapped
    when destroying a GtkClutterActor.
    
    GTK+'s invariants checks expect children to not be visible anymore
    if they're not mapped. This can happen if we don't forcefully hide the
    GtkClutterActor's widget before unrealizing it.
