No need to clear the style resolver in Document::childrenChanged

No need to clear the style resolver in Document::childrenChanged

If you delete the documentElement then that also means all <style> and
<link> elements must have been removed from the document so the
StyleResolver should already be reset or cleared and we don't need to
call clearStyleResolver() from inside Document::childrenChanged.

What if you have multiple element children of the document?

You can't, that's forbidden:

// Documents may contain no more than one of each of these.
// (One Element and one DocumentType.)

I don't think that's possible. Document::childTypeAllowed disallows having more
than one DocType or more than one Element child of the document.
