    directory: Treat as empty if no file is to be shown
    
    Directory is reported as not empty if it has files, even if all of them
    are hidden and not shown.
    
    As nautilus_list_model relies on this information to label expanded
    subdirectories as empty, the dummy row is stuck on "loading..." if
    subdirectory contains only hidden files and they are not to be shown.
    
    Instead, a directory should be reported as not empty only if we any of
    its files are to be shown.
    
    Fixes https://gitlab.gnome.org/GNOME/nautilus/issues/39
