Reviewed by Chris Dumez.

This patch aligns WebKit with Gecko / Firefox, Blink / Chromium and Web-Spec [1] [2].

Merge: https://chromium.googlesource.com/chromium/blink/+/2f46be9abd9350909c03b95b2597ee164d1c38b8

Previously, WebKit was adding the new element before the first node, instead
of before the first `tr` (for insertRow) or `td` / `th` (for insertCell)
element.
