Charge object count when object is created, no matter if the object is initialized or not. Charge the remaining quota when the object is initialized. Also, checking initializer.Pending and initializer.Result when determining if an object is initialized. We didn't need to check them because before 51082, having 0 pending initializer and nil initializers.Result is invalid.
