This patch is to add early return condition to endOfSelection whether it has
rootEditableElement since L177 does not take assumption about this via endingSelection() in endOfSelection.

* Source/WebCore/editing/InsertListCommand.cpp:
(InsertListCommand::doApply): Add early return about "rootEditableElement"
* LayoutTests/editing/execCommand/insert-ordered-list-crash2.html: Add Test Case
* LayoutTests/editing/execCommand/insert-ordered-list-crash2-expected.txt: Add Test Case Expectation
