(15.20.0.3) Perform an update of knowledge graph on any applicable collections to ensure "mention" relationships that reference themselves are removed.

(15.20.0.7) As wcag was deprecated in version 15.12 it is recommended to switch to using its replacement by editing collection.cfg to have 'wcag.check=false', remove FAChecker from 'filter.classes=' and set 'accessibility-auditor.check=true'. The wcag check may be completely removed from future versions.

Start the Jetty web server if the server was not restarted.
