Components again not working

[sverhagen]

The change in 24227a1efe9e3d241e3cfb02af086d8889be5baa makes the plugin not work for components anymore, due to $article->introtext always empty, thus the entire thing ignored in MusicTagsHelper.

The problem is the following check in MusicTagsHelper.php:

if (isset($article->introtext))

It appears that introtext does not exist in component texts.

I think the correct version should be:

public static function getMusicTagsFromArticle($article) {
  $matches1 = array();
  $matches2 = array();
  if (isset($article->introtext)) {
    $matches1 = self::getMusicTagsFromText($article->introtext);
  }
  if (isset($article->text)) {
    $matches2 = self::getMusicTagsFromText($article->text);
  }
  return array_unique(array_merge($matches1, $matches2));
}
