In some situations we could end up not with lingering 'view-loaded' handler. This could result in delayed spring animate-in being initiated, e.g. after a minute after the activities overview was already closed. Fix this by removing any lingering signal or later handlers when unmapping. Fixes: 5c33fe4a0a4eb4ed https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1155
