Even though this isn't strictly necessary anymore, it still tests the contents
of the renewal message so I restored the check and just dropped the "PREFIXED"
part. We can remove this later if we want.

     Utils.failTest('license-renewal message doesn\'t contain expected header',
-                   PREFIXED_EME_RENEWAL_MISSING_HEADER);
+                   EME_RENEWAL_MISSING_HEADER);
   }
