Assets with the same id as their containing folders problematic on export

[Eric Casteleijn]

When doing a full media export of a Silva Folder containing an asset (tested with image) with the same id, Zope acquisition messes up, and an asset adapter is looked up for the folder, which fails.

traceback:

Exception Type TypeError
Exception Value ('Could not adapt', <Silva Folder instance ibm>, <InterfaceClass Products.Silva.adapters.interfaces.IAssetData>)

Traceback (innermost last):

This have been fixed during the XML import/export cleanup.
