Description
Some objects don't work well with literal languages:
- ZMonolingualStringSet
- ZMultilingualStringSet
- ZMonolingualString
- ZMultilingualString
- ZErrorFactory --> broken create invalid lang error
Steps to reproduce:
- Calls to Fetch Wikidata Item return languages in their literal form, when PHP expects references
- e.g. http://localhost:8080/w/api.php?action=wikilambda_perform_test&format=json&wikilambda_perform_test_zfunction=Z6821&wikilambda_perform_test_zimplementations=Z6921&wikilambda_perform_test_ztesters=Z23746&uselang=en
