    appDisplay: Call super.vfunc_unmap last
    
    So as to guarantee the unmapped state sticks and doesn't get toggled
    back to mapped before we return.
    
    Being in a mapped state when `FolderIcon.vfunc_unmap()` returned was
    causing an assertion failure in `clutter_actor_set_mapped` and crashed
    the shell.
    
    Closes: https://gitlab.gnome.org/GNOME/gnome-shell/issues/2170
