Steps to reproduce (*)

1. Set up async mails sending
2. Buy a product, create order, invoice or shipment
3. Send sales mails
4. Remove product (along with configurable(parent) product)
5. Try to resend sales email (e.g. set column email_sent to Null in relative tables)
6. or try to send invoice/shipment again
   

Expected result (*)

1. Emails are send
2. If there are newer sales items planned to send (email_sent is null) emails will be sent
3. Job code shows warning or problem item is ignored but newer items are sent

Actual result (*)

1. Emails are not sent
2. If there are newer sales items planned to send (email_sent is null) emails will not be sent; It leads that sales async mailing stop working
