AK: Oops, the optimization in Vector::append(Vector&&) was broken.

Browse source 
It forgot to clear out the moved-from vector. It's easy to see where this bug
came from: I assumed m_impl was an OwnPtr. It would be comfy if move() on some
arbitrary T* would also null it out but alas that's not how things work.
