 [31699] caused the Comment button to disappear in some themes.

 As reported by @tellyworth in [comment:33:ticket:15015]:

 > Just FYI we've come across a handful of themes that were affected by
 this. They were filtering `comment_form_defaults` and building a fresh
 $args array from scratch, so the new submit elements were not included in
 the return. That left them with no Submit Comment button.

 Seeing some similar reports on support forums. Here's an
 [https://themes.trac.wordpress.org/browser/my-
 life/0.3/library/functions/comments.php#L165 example] in
 [https://wordpress.org/themes/my-life/ My Life] theme.

 We should make sure that `'submit_button'` and `'submit_field'` are still
 in the array after it's filtered.
