[GtkFileChooserButton] bgo#645065 - Restore the previously-selected file when the button's GtkFileChooserDialog is canceled

The file chooser is asynchronous, so doing 'select_file (old_file)' and subsequently querying
the file for updating the labels is not going to work.  However, the underlying file chooser
will emit 'selection-changed' as appropriate when it finishes restoring the old file.  So,
we only need to update the labels when the file chooser dialog is confirmed, not cancelled.
