    filechooserbutton: In SELECT_FOLDER mode, consider an empty selection to mean current_folder
    
    If the user didn't explicitly select anything, BUT the file chooser button has
    a current_folder set, do the same as what GtkFileChooserDefault would do:
    return the current folder as the selection.
    
    This makes the tests in tests/filechooser pass!
