When $user = $order->get_user(); is empty, $user->test_omise_customer_id or $user->live_omise_customer_id will throw attempt to read property test_omise_customer_id from null.
So we need to check user is not empty before we get value from user.
3. Quality assurance
Create manual order with guest user from admin panel and use customer payment page link to make payment where user is not logged in (eg. try with different browser).
