While creating an order, if we remove an item after adding, `pre_post_update` hook gets called. Since the order is not created yet, `$order->get_date_created()` will be null, and this will cause a fatal in the event tracker which checks for and tracks edit in order created date.
We now return early when order status is `auto-draft` to prevent these kind of errors.
