Fix printing of event detail in python events demo program

The events demo program is slightly misleading printing

  myDomainEventCallback1 EVENT: Domain f14i686(-1) Added

which is not distinguishing Add vs Update events. It should have
been doing

  myDomainEventCallback1 EVENT: Domain f14i686(-1) Defined Updated

* examples/domain-events/events-python/event-test.py: Fully print
  event detail info string
