* creates notifications (& mails) that link to the board
* * ReferenceExtractor.php (run from ReferenceRecorder.php, a post
* listener) needs to parse content with Parsoid & for that it needs
* the board title. AbstractRevision::getContent() will figure out
* the title from the workflow: $this->getCollection()->getTitle()
* If you even feel the need to change the order, make sure you come
* up with a fix for the above things ;)
