Currently, the EDI attachments *content* is passed to the Send & Print wizard.
Then, the wizard re-creates these attachments and link them to itself. At the
end of the flow, when clicking 'Send & Print' button on the 'Send & Print' wizard,
the attachments of the wizard are copied on the move.
Thus, the EDI attachments are duplicated.
Passing the ids of the EDI attachments rather than the content solved the issue,
since they are simply linked to the wizard, without being re-created.
