    gdm: fix empty user list on user switching
    
    There's some vestigial code for hiding the user list
    that runs at the same time its parent is hidden.
    
    Only the parent should be hidden, at this point, so
    there's situations where the user list hides and
    never comes back.
    
    This commit fixes that, by deleting the vestigial code.
