Run revisison tests with `@graph` also since revisions seem broken when @graph is used

[bbrala]

I don't think revisions work with the @graph contruct. Could perhaps the following data be tested also? That should test the other contruct and probably show that revisions do not work. Guess an updated copy of w-certificate.service.new-schema-revisions.spec.ts with some small adjustments for the graph.
