We now null out smart pointers *before* calling unref on the pointee. This ensures that the same smart pointer can't be used to acquire a new reference to the pointee after its destruction has begun. I ran into this when destroying a non-empty IntrusiveList of RefPtrs, but the problem was more general so this fixes it for all of RefPtr, NonnullRefPtr, OwnPtr and NonnullOwnPtr.
