Commit wide comments does not update after submit or delete is clicked.

The UI doesn't update from the form to the comment div. The comments do get sent to the server, but user doesn't get the feedback. So the user will probably spam the submit button a few more times before giving up.

Looks like during the changes for side-by-side, you had to alter both of the comments whenever there were changes like submit or delete, and the way you're looking them up is broken for commit-level comments. For example, line 171 of commit.coffee:

form = $(e.currentTarget).parents(".file").find(".commentForm[form-id='" + formId + "']")
