Comments: Escape comment author's email in the Edit Comment form.

Technically, this is redundant, as the `comment_author`, `comment_author_email`, and `comment_author_url` fields are already escaped via `get_comment_to_edit()` before the form is displayed. 

However, this brings some consistency with the `comment_author` and `comment_author_url` fields being escaped in the same form.

Follow-up to [11721].
