Fix regression on metadata uri

e9f120141c8d2a1404660e46ce2126c83521405d caused a regression on this
that can be seen from the find and replace.  Unfortunately service
validator doesn't catch this, but protocol validator does.

Tested: Run redfish protocol validator and see this test is now passing.
