fix(trovesearch_denorm): whole-iris field names

retain the entire iri for path-based field names --
this makes them easily reversible for highlighting fields that match

(previously used "sufficiently unique" iris like "://foo.example/blarg",
which works well enough, except it'd take knowledge to get the original)

(bug introduced in 7b68b96 )
