Deleting a WP user without without a CAP term is throwing a fatal

[kariae]

When running a wp_delete_user( $user->ID, $reassign_to ) the delete_user_action action is triggered. For WP users without CAP terms this action throws a fatal error:

Warning: Attempt to read property "term_id" on bool in /path/to/wp-content/plugins/co-authors-plus/php/class-coauthors-plus.php on line 1121

When I checked these lines, $this->get_author_term can return false, and in this case we shouldn't delete the term because it doesn't exists.
