Title: Remove unnecessary merging from child context to the context

CoreData implementation will push the saved changes from child context to the parent context when save.

So I think the merge change from childContext to the context code is unnecessary and also make the leaked on the observer (addObserverForName:object:queue:usingBlock: return the observer object for remove it from the Notification Center later)

Please read: "Core Data Release Notes for iOS v5.0" documentation for more information.
