dct:rightsHolder issue between dataset.rdf and catalog.rdf

[tdipisa]

We have differences on dct:rightsHolder between the dataset specific RDF output and the dataset RDF output in catalog.rdf

A sample dataset in client instance here

The output of

http://test-dati.retecivica.bz.it/dataset/servizi-webservice-sasa.rdf (the correct one)

is the following:

<dct:rightsHolder>
  <foaf:Agent rdf:nodeID="Na91865bc14c94c2b80ed890ccfed8cec">
    <foaf:name xml:lang="de">SASA Bus</foaf:name>
    <foaf:name xml:lang="it">SASA Bus</foaf:name>
    <rdf:type rdf:resource="http://dati.gov.it/onto/dcatapit#Agent"/>
    <foaf:name xml:lang="en">SASA Bus</foaf:name>
    <dct:identifier>00359210218</dct:identifier>
  </foaf:Agent>
</dct:rightsHolder>

The output in catalog.rdf is the following:

    <dct:rightsHolder>
      <foaf:Agent rdf:nodeID="Ne8276a2d39fe43dd993e46a33fb2b11f">
        <foaf:name xml:lang="it">SASA SpA</foaf:name>
        <foaf:name xml:lang="en">SASA Bus</foaf:name>
        <dct:identifier>tmp_ipa_code_26</dct:identifier>
        <foaf:name xml:lang="de">SASA SpA</foaf:name>
        <foaf:name>SASA Bus</foaf:name>
        <rdf:type rdf:resource="http://dati.gov.it/onto/dcatapit#Agent"/>
      </foaf:Agent>
    </dct:rightsHolder>

This was probably because catalog.rdf uses a bit different code path (involing package_search instead of package_show) to get list of datasets. This was passing dataset locality check, and generating wrong results in the end.
