[YouTube] Add ability to use the guide endpoint to get a visitorData

Some clients like TVHTML5 are not allowed on the visitor_id endpoint
(with this client, a 400 HTTP response is returned with a precondition
check failed error).

Also disable pretty printing for these requests, like we do for others.
