Wikidata Query Service Timeout handling

The behavior in case of a Wikidata Query Service timeout is:

 EndPointInternalError('EndPointInternalError: endpoint returned code 500 and response. \n\nResponse:\nb\'SPARQL-QUERY: queryStr=PREFIX pq: <http://www.wikidata.org/prop/qualifier/>\\nPREFIX p: <http://www.wikidata.org/prop/>\\nPREFIX wd: <http://www.wikidata.org/entity/>\\nPREFIX wdt: <http://www.wikidata.org/prop/direct/>\\nPREFIX wikibase: <http://wikiba.se/ontology#>\\nPREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>\\nSELECT DISTINCT\
