CSW / iso19110 / exception when requesting ISO19139 output

[Fxp]

Test :

• Create an iso19110 record
• Run CSW query :

  <?xml version="1.0"?>
  <csw:GetRecords xmlns:csw="http://www.opengis.net/cat/csw/2.0.2" service="CSW" version="2.0.2"
      resultType="results" outputSchema="csw:IsoRecord">
      <csw:Query typeNames="gmd:MD_Metadata">
          <csw:Constraint version="1.1.0">
              <Filter xmlns="http://www.opengis.net/ogc" xmlns:gml="http://www.opengis.net/gml"/>
          </csw:Constraint>
      </csw:Query>
  </csw:GetRecords>
  

Error is:

<ows:ExceptionText>Raised exception while getting metadata :javax.xml.transform.TransformerConfigurationException: Requested transformation [.../geonetwork/xml/csw/schemas/iso19110/iso-summary.xsl] does not exist.</ows:ExceptionText> 

Fix:

• Do not return iso19110 records when output format is iso19139 (like fgdc or dc records)

Quick fix in r6680, but we should probably add ​http://www.isotc211.org/2005/gfc to the list of outputSchema for CSW response.

r6682 in branch 2.6.x
