I missed this in the previous patch.

I don't think we can ask the user to remove a broken link in JBS. I'm pretty sure that would require admin actions. Here we should just treat it as if the link didn't exist and remove the label.

I missed this in the previous patch. The language of this reply needs some work. Here is my suggestion.

"The CSR requirement cannot be removed as there already is a CSR associated with the main issue of this pull request. Please withdraw the CSR [link] and then use the command '/csr unneeded' again."
