TEST: description-logic-668

Jeremy - description-logic-208 *had* in it's conclusion
  oiled:V16448 rdf:type oiled:C122.
(which is now removed and in nonentailment test 209)
The observation is that that triple is actually also
gone from the conslusion of description-logic-668
which is why we pass it :-)
