I'm not sure why name and uniqueName aren't allowed on WebRemoteFrame.  We
already have setReplicatedName, which kind of gets around these
ASSERT_NOT_REACHEDs.  Names might be something that belong on Frame rather than
LocalFrame?

Actually, let's try to limit the API surface of WebRemoteFrame. Since we're
implementing this in web/, we can just reach directly into blink::Frame::tree()
to get the name and uniqueName.

Ok, will do.
