prepare ingest of schaubühne data

[csae8092]

there is a listperson with wikidata-ids; and a listbibl with a similar structure as insel-data; so I'll prepare an ingest of all persons (with wikidata id) and all the works written by those

Maybe before batch-importing persons via wikidata the importer-bug could be fixed? there are forenames duplicated in the surnames. The problem seems to derive from this:
http://www.wikidata.org/entity/Q2835019
This element does not have a surname-field so it takes the title of the item as surname. It should remove the given name from the title before doing so.
