Remove outdated non-relevant comment.

1. We have utilities for proper escaping of quotes, so the comment is

2. Revert should work with the submissionid (ie. everything that was
   submitted together (includes topics + ancestors and their topics
   recursively). So the comment about topics not working is not
   relevant.
