Steps to replicate the issue (include links if applicable):
- find an Item that has both a label and a description set in a specific language
- replace the label (or description) with a PUT request to /wikibase/v0/entities/items/{item_id}/[labels|descriptions]/{language}
- send the same PUT request again
What happens?:
- HTTP response with status "400 Bad Request"
- error code item-label-description-duplicate
- error message: "Item '{item_id}' already has label '...' associated with language code '{language}', using the same description text"
What should have happened instead?:
- HTTP response with status "200 OK"
- new label in the response body
