    files-view: Stop connecting to GtkFileChooser::current-folder-changed
    
    The signal is gone in GTK 4.
    
    We have been using it to disable the action button if the destination
    is a descendant of selection, which is not allowed for copy/move.
    
    Ideally, we should reimplement this feature as a mode in our main
    window, instead of using a file chooser. Until then, we can rely on
    our file operations code to impede and warn about a copy-move operation.
