Appending a node to an Element after empty() throws an Index out of bounds

[jhy]

String html = "<div><p>One<p>Two<p>Three</div>";
Document doc = Jsoup.parse(html);

Element div = doc.expectFirst("div");
Element p = div.expectFirst("p");
div
    .empty()
    .appendChild(p);

Produces Index 0 out of bounds for length 0

Root cause is that after emptying, the child still has the original parent, and then on reinsert into the same original parent, the replacement / move code breaks.

Fixed by explicitly clearing the parent node from the removed children.
