Wrong value for "custobar_created_at" sales order

[imarmo]

Hi,

This getCreatedAtDate dosen't exist and always returns null.
formatDate returns current date and not order created at date.

magento2-plugin/Model/MappedDataBuilder/DataExtender/SalesOrder/AddBasicData.php

Line 28 in b66b300

'custobar_created_at' => $this->formatDate((string)$entity->getCreatedAtDate()),

getCreatedAt should be used instead
'custobar_created_at' => $this->formatDate((string)$entity->getCreatedAt()),

Thanks
