Upgrade fails if leaf type is extracted to a separate hierarchy

[GoogleCodeExporter]

Subj.

Old code:

public class ProductionServiceProvisionActService : SevRGasEntity {
  ...
}

New code:

[HierarchyRoot]
public class ProductionServiceProvisionActService : Entity {
  ...
}

Buggy code:

var typeIdField = type.Fields.Single(f => f.IsTypeId);
var targetType = typeMapping[type];
var targetTypeIdField = targetType.Fields.Single(f => f.IsTypeId);

Likely, the exception is thrown @ the last line.
