    window-slot: fix search state when going back/forward
    
    When a search is performed, Nautilus adds it to the history
    stack, and we can return to it through the back or forward
    buttons.
    
    While we can indeed go back to the search, the UI components
    such as the search bar doesn't update accordingly, leaving us
    with a search directory without a search bar.
    
    Fix that by properly checking the search-visible action state.
