Fix iterator position resetting Previously, when an array was converted from packed to hashed, iterators would not be correctly reset to 0. Similarly, removing the last element from an array would decrease nNumUsed but not actually fix the iterator position, causing the element to be skipped in the next iteration. Some code was also removed that skips over IS_UNDEF elements for nInternalPointer and iterator positions. This is unnecessary, as this already happens during iteration.
