[Fix] Yoast SEO default settings for Sugar Calendar recurring events

/**

 * Give Yoast SEO default settings for Sugar Calendar recurring events, so the

 * Yoast SEO > Settings > Content Types > Recurring Events page loads instead of

 * showing "t.split is not a function".

 * Edition: Sugar Calendar Pro (recurring events are Pro only). Harmless on Lite.
