When refreshing an existing unix folder, turn off its is_finished_loading state

	* gtk/gtkfilesystemunix.c (gtk_file_system_unix_get_folder): When
	refreshing an existing folder (i.e. when we are about to reload
	its file list), turn off the folder's is_finished_loading flag.
	Otherwise callers which do ::is_finished_loading() followed by
	::list_children() will get nothing.
