 * Fix flag configs with empty labels.
 *
 * Flag lists (flag_lists) can create relflag_* flag configs without a label.
 * Core 10 silently tolerated NULL labels, but core 11 typed
 * Html::escape() as string, which makes \Drupal::token()->getInfo() fatal
 * (the flag tokens build t('@flag flag link', ['@flag' => $flag->label()])).
 *
 * Give every flag a string label: the related flagging collection name when
 * available, the flag ID as a fallback.
