docs: We update the tags after the Post was inserted.
  We update the tags before the Post was updated, see `onSaving` event.
  `onCreated` is called before `onSaved`.
  
  `onSaved` is the last event in the line - triggered for updating or inserting data.
  bookshelf-relations listens on `created` + `updated`.
  We ensure that we are catching the event after bookshelf relations.
