During the "normal" callback for new and old values, the ofObject: parameter passed to the observer is the original receiver of the addObserver:forKeyPath:options:context: call, but that isn't the case with the call caused by the CPKeyValueObservingOptionInitial option. This commit uses _targetObject, the receiver of the addObserver:... call, rather than self, the _CPKVOProxy.
