Remove EventManager reset methods, because they violate encapsulation....

Remove EventManager reset methods, because they violate encapsulation. The whole idea of the EventManager is that you can register hooks without worrying about what hooks other pieces of code might be registering. The reset methods violate this separation of concerns, since they will blow away everyone else's hooks too. (See gh-6680 for an example of this breaking things.) Since there is never any safe way to use them, we simply remove them entirely.
