WIP: Filesystem Document modules compatibility
Fix the issue that very old instances of document classes still using Products.ERP5Type.Document.GeographicAddress.GeographicAddress
as __class__
were broken since GeographicAddress
is now moved to document component.
And also the issue that even older document classes using Products.ERP5.Document.Account.Account
( not even from the dynamic Products.ERP5Type.Document
module but from their "physical" dotted name )
