checkWorksDBPedialinksRelations test failed

[zazi]

This test (see [1]) fails currently for some reason. The proof id should deliver two results. However, the SPARQL query delivers only one result. The rather equal Wikipedia query works so far. The description of the related resource shows the correct mapping via the SNORQL interface, see http://localhost:2020/snorql/?describe=http%3A%2F%2Flocalhost%3A2020%2Fwork%2Faacb1ab0-c740-436a-a782-ed60026cf82b%23_
However, the SNORQL interface shows a similar (wrong) behavior for the following SPARQL query:

WHERE { ?workURI rdf:type mo:MusicalWork ; 
     owl:sameAs ?dbpediaURI ; 
     mo:musicbrainz_guid "aacb1ab0-c740-436a-a782-ed60026cf82b"^^xsd:string . 
     ?dbpediaURI is:info_service isi:dbpedia . }

The checkWorksIBDblinksRelations shows a similar behaviour.
