NewWindowDelegate::OpenFeedbackPage can only be used to open the
feedback dialog in the active user session.
SigninScreenHandler::HandleSendFeedback is used to open the feedback
dialog in the login screen. Due to the effort to create the instance of
SigninScreenHandler, this cl triggers the same handler associated with
the feedback accelerator from the login screen to bring up the feedback
dialog.
