  Log Message:
  -----------
  Cleanup ZApplicationWrapper.

Remove unused klass_args argument and avoid aborting transactions if
none is active. The publisher should always commit or abort the
transaction, so the Cleanup instance in `REQUEST._hold` shouldn't need
to abort anything. This gets rids of debug log messages, where each
request opens and aborts a secondary transaction.
