Follow-up to #130. Improve the results of the wikidata matching.

  • 259.456
• Wieviele distinkte Orte sind das?
  • 4975

As discussed offline:

• We won't query the Wikidata API anymore as fallback because all resources we need should be in the set covered by the SPARQL query. If they are not in there, something has to be corrected at Wikidata. (With this, we also won't have distinct Wikidata sets for the lobid data and the visualized classification entry.)
• We will add the label from the superordinated administrative (P131.rdfs:label""@de ) to the ES geo index and this will lead to matches for a lot of strings in currently not matched (e.g. "Ahaus Ottenstein" & Q615951.
