Changeset [0ce115bc9c44199ce52510e445ebce030d92431d] by Brian Donovan

Ensure observeValueForKeyPath:ofObject:change:context is called consistently.

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.
