Fix for 4.4

I see you’ve added this for 4.4:

global $post;
// Quick fix: $post no more available since WordPress 4.4
if ( is_null( $post ) )  {
		global $wpdb;
		$_postid = $wpdb->last_result[0]->ID;
} else {
		$_postid = $post->ID;
}

I think this might be more reliable instead of using $wpdb:

$_postid = $commentdata['comment_post_ID']

The post ID related to that comment should already be available in the $commentdata array. ??

I added this as a patch initially, which fixed the 4.4 issues, but then downloaded your patch and it stopped working again. So this might be more reliable for other people as well.

Thanks!
