Fix Document.getElementsByTagName to return the root node.

I introduced this regression when changing Element.getElementsByTagName
to not return itself. Note that one of our tests (GetElementsByTagNameNS)
had the wrong expectation here; the new result is consistent with the RI.

Also fix a related problem in InnerNodeImpl which assumes the document
field is always non-null. It can be null for Doctype nodes!
