Don't show setup hint on empty profile search

manage_profiles list with a query but no limit/offset used the
full-inventory empty text ("No profiles found... use setup") even when
the search simply matched nothing while other profiles exist. Pass the
query through so an empty search returns a "no matches" note instead,
matching the paginated path's neutral empty result.
