Andreas Kling b62043dbca LibWeb: Protect LayoutCheckBox against crashes after event dispatch ...

After dispatching a "change" event due to the checked state being
modified, we may have been removed from the layout tree.

Make LayoutCheckBox protect itself to prevent this from crashing.

Also, add a little test page for checkboxes. :^)
