Title: Only apply the metadata backwards-compability shim if necessary

i.e. if the fields query string parameter is empty or missing, or if the fields query string parameter mentions fields requiring backwards-compatibility. If my query looks like `fields=chambers`, it means I just want `chambers` not all the backwards-compatibility fields. This fix doesn't break backwards-compatibility.
