Run the original operation before we update linked attrs
This causes the linked attribute modifies to occour after the original
operation is entered in the transaction (any failure still fails the
lot). This means (I hope) that we can have another module search the
originating record when the backlink is created, filling in the GUID
and SID for the extended DN.
