[FIX] mail: set message_main_attachment_id to copy=False

Create a record.
Add an attachment set as message_main_attachment_id (e.g. through log note).
Duplicate that record.
The new record has the message_main_attachment_id of the old record,
while it has no attachments.

Since attachments security is linked to the record id, we shall not copy them.
