A wiki I'm an admin on has the exact same problem. The comments are very sensitive, but I think it's possible to use certain settings to get them all to rename. If you leave both "Rename subpages" and "Leave a redirect behind" unchecked, I think it moves all the comments. You might have to experiment with it, though. If it doesn't work, you can try contacting Wikia to move the rest of the comments (or move them by bot, which I think can also be used to fix ones that got left behind in moves).
