Done button should use OID link, not ThingId

(Bug, Closed -> Fixed, Priority: High, Test Status: No automated tests yet , Reported By Justin du Coeur, )
Summary: Currently, the Done button of the Thing Editor uses the ThingId for linking. Problem is, we might be editing the Name field, in which case the page then comes up as an unknown name when we press Done. So this is an example where using the hard link is probably more appropriate.
