Deal with inconsistencies in data for Keyword categories
In preproduction, we have some duplicate entries for Names, it should not return any logs in production though!
The command to run:
$ DJANGO_SETTINGS_MODULE=anthology.settings.local python manage.py load_keywords_categories_from_distant_csv --url=https://framagit.org/anthologie-palatine/anthologyontology/uploads/871a295fa3da4c9dd5b42bdfd3004cc6/KeywordsLangue_2_.csv
Closes #220 (closed)
