Fix entries for originator

[joergreichert]

currently the entries are: dezernat, fraktion, und, die bau, stadtentwicklung, linke, gesundheit, jugend, soziales

Performing the following query against SQLite database select originator, count(name) as paper_count from papers group by originator having paper_count > 1 order by paper_count desc

gives: originator.xlsx

This could be maybe fixed by deactivating the tokenizer / analyzer for field originator in ElasticSearch mapping

was already fixed by adding not_analyzed. Had forgotten to rebuild the index.
