binding: Fixes the fallback mechanism of Document's named properties.

The old implementation only works for
a) there is a hidden prototype, and documentWrapper->GetPrototype()
  actually returns itself, or
b) fallbacked attributes are data-type properties.

Since we made attributes be accessor-type properties _and_ removed
the hidden prototype, the old implementation no longer works.

Fixed the issue using V8's GetRealNamedPropertyInPrototypeChain().
