Use 2 FormTypes for 1 Entity

Doesn't work properly. Creates a new master entity (for example a new ProductPage entity when saving a productpage entity). It does however save properly in the kuma_seo table, also under a new record.
don't require extrametadata
Add meta_title + add get_title_for twig extension
Add og:url, linkedin url & productID to social

Modified metadata rendering behavior. Secondary parameter is now the active node.
