REST API: Fix bug where comment author and author email could be an empty string when creating a comment. 

If the `require_name_email` option is true, creating a comment with an empty string for the author name or email should not be accepted.  Both values can be an empty string on update.

Merges [39444] into the 4.7 branch.
