[FW][FIX] document: audit trail with document versionning

Normally, when using document versioning, the attachments linked to a record are re-attached to the document when changing the version. This is not compatible with the requirement for audit trail in Germany (GoBD) as we want to be sure that the document won't be deleted. This is ensure by making sure all the attachments stay attached, and can't be deleted.

To reproduce:
* Install Accounting and Documents, as well as l10n_de
* Select/configure a German company
* Create new document folder settings for Customer Invoices
* Create a new invoice
* Send & Print
* Delete it from the attachments (it should "detach it")
* On the document, change the main history version, or on the invoice, navigate through the attachments
