    files-view: Stop setting custom filechooser filter
    
    We set a custom filter to prevent selecting a folder that's part of the
    selection as the destination to move that selection.
    
    GTK 4 doesn't support custom filters, and the available options don't
    fit this purpose.
    
    Just remove it. It's safe: we popup an error dialog saying you can't
    move a folder into iself. Of course, it would better not to allow the
    user to make this mistake, but let's we can't have everything.
