When changing an item's content with the wbeditentity API, the extension always uses 'wikibase-item-summary-wbeditentity-update' as autocomment, while it should autodetect changes and use, e.g. 'wikibase-item-summary-wbsetlabel-add', 'wikibase-item-summary-wbsetdescription-set', etc.
Also for adding/editing claims, references and qualifiers.
so we could avoid workarounds like Gerrit change https://gerrit.wikimedia.org/r/#/c/130811/
