Supporting object reset while its properties are being iterated would increase complexity for little benefit. Furthermore it may not be possible to ensure a consistent behavior between ghosts and proxies (wrt to iteration position). Iteration is detected by checking if the object's properties ht has iterators. This requires refactoring the hooked get_iterator() implementation to ensure that it creates a properties ht iterator immediately. Closes GH-15960
