thiemowmde c02595bb97 Drop obscure error message about an unused group ... The message was part of the original patch that introduced the group feature in 2009, see https://phabricator.wikimedia.org/rECIT75004e33. Notice how there was never a test scenario for this message. A test was added in 2020 via I07738cc. The message appears only in a rare edge-case when a group is entirely unused in the text, and only when the group is not empty. The shortest possible example is: <references group=g> <ref group=g name=a>a</ref> </references> Just adding something unrelated like `<ref group=g>x</ref>` to the text changes the error message. Now the group is "used". But this notion is confusing to begin with. References can be part of a group, and we can use references, but we can't use groups as if they are a separate entity. A better error message already exists. Notice how this special error message doesn't appear anywhere in the Parsoid code path. That was already using the other, more generic error message.
