Editor should use reference-getting document() internally.
<https://webkit.org/b/122364>
Reviewed by Darin Adler.
Instead of grabbing at Editor::m_frame.document(), use the nice
Editor::document() helper that always returns a Document&.
Calling Editor methods on a Frame's editor() while there is no
Document in the Frame is a programming error and this is covered
by an assertion in document().
This removes a bunch of null checks and enables further cleanup.
