event(evt) should not convert falsy evt to empty Object

It is perfectly possible for a Lambda function to be passed a falsy event (e.g., a null, false, 0, etc.). Therefore, it is not valid for event(evt) to convert falsy arguments to an empty Object, as that would completely change what was intended.
