- Fix random failures in testBusinessTemplate on Zope 2.12
- Do not sort record per 'id' anymore because it was a noop:
  first value returned by reorderPickle is not the object but its state,
  so "getattr(o, 'id', None)" was always None
- By reducing the number of calls to reorderedPickle/XMLObject, exportXML
  function is now much faster.
