updateOrCreateFromFields is made to call updateOrCreateFromKeyName.
updateOrCreateFromFields called self._model.get_or_insert which only creates
new entities but doesn't update the properties if the entity already exists.
So updateOrCreateFromFields is now made to call updateOrCreateFromKeyName
which actually updates the entity properties if entity already exists.
