Peter Wilson 339d838475 Comments: Check if wp_new_comment() returns an error. ...

Adds checks throughout to allow for `wp_new_comment()` returning a `WP_Error` instance.

Updates the docs for the `pre_comment_approved` filter to include that it can be passed an error.

Props enrico.sorcinelli, ryotsun.
