Fix bug in the code review tool when readding a discarded comment
https://bugs.webkit.org/show_bug.cgi?id=74450
Reviewed by Adam Barth.
If you discard a comment that has a corresponding previousComment,
then we would incorrectly remove the comment baseline. So, the next
time you added a comment by clicking on the previousComment, we
would get undefined as the start line for the new comment.
All of this works fine until you try to restore the comment from
localStorage, at which point we throw an error because the start
line is undefined.
Also added some failsafes to better handle the case of corrupted comments.
