Unsubmitted comments are saved to the cookie storage when signed out
so that they can be recalled upon next sign-in. If on next sign-in a
draft comment should be updated, that was deleted in the meantime, the
request to update the draft comment fails with '404 Not Found'. This
results in displaying the following error to the user.
"Code Review - Error
The page you requested was not found, or you do not have permission
to view this page."
Since the comment was not removed from the cookie storage, the user
got the same failure on next sign-in again.
Since the comment was deleted it is safe to ignore these failures and
to remove the inapplicable unsubmitted comment from the cookie
storage.
