Fixes three issues in ExpressionHelper: - Current Value was not retained when changing from SingleChange to Generic, this can lead to missed changes - Current Value was not retained when changing from Generic to SingleChange, this can lead to missed changes - Current Value was not cleared when last change listener was removed in Generic variant, resulting in an older value being referenced and not becoming eligible for GC until either a ChangeListener is added again, or sufficient InvalidationListeners are removed to switch to the SingleInvalidation implementation...
