Unknown language code ‘nl’ (must be one of [‘fr’, ‘de’, ‘en’])

This error came because lino_welfare.settings.Site.setup_choicelists() specifies ` hidden_languages=’nl’` but Chatelet had no language ‘nl’.

lino.modlib.languages.fixtures.all_languages didn’t work because it still tried to import Language from countries.
