$wpdb->get_var() — empty sting becomes a NULL — at Initial Version

Because of the following condition, we get NULL, even if a real field value is an empty string!

return ( isset( $values[ $x ] ) && $values[ $x ] !== '' ) ? $values[ $x ] : null;

[See wp-db.php Line 2477](https://wp-kama.ru/filecode/wp-includes/wp-db.php#L2460-2478)

I think it is better to delete $values[ $x ] !== '' check and return field value as it is if it exists - what is usually meant by NULL in PHP (empty string is not null!).
