Use the "destroy" MetaWaylandSurface signal instead of the wl_resource destroy signal for tracking the lifetime of the surface with pointer focus. As unsetting the focus may have side effects due to handlers of the "focus-surface-changed" signal, connect the signal after the default handler to make sure other clean up facilities have the chance deal with the surface destruction before we try to unset the focus. https://bugzilla.gnome.org/show_bug.cgi?id=783113
