1. searchDataproviders.service.ts & searchProjects.service.ts: Updated parsing of description (like in services for landing, use ParsingFunctions.parseDescription()).
2. searchFields.ts: Added in OpenaireEntities enum values for type names in files.
3. open-aire-jsonld-converter.service.ts:
a. Updated parsing of description in methods convertProject() and convertDatasource() - use ParsingFunctions.parseDescription().
b. In convertDatasource() method set "otherUrl" (not push it) in sameAs (on next commit, dataprovider landing sents all provenance urls as array).
4. jsonld-document-serializer.service.ts: [Bug fix] Added check in "serializeDescription()" method.
