remove this and the "type". if you really need it, you can do the logic in
PromiseEvent.prototype.type:

if (!this._status)
  return "new";
else if (this._promiseParent)
  return "chain";
else
  return "update";

Removed this as we can tell the type of event using status and parent on
backend.

+      %DebugPromiseEvent({ type: type,
                            promise: promise,
                            status: status,
                            value: value });
