[empathy/gnome-2-34] Don't start the Call when the streams start

[Emilio Pozuelo Monfort <epm src gnome org>]

commit 15761dfafa40dce3e5acb2f9fecc5b808fa11e47
Author: Emilio Pozuelo Monfort <emilio pozuelo collabora co uk>
Date:   Tue Mar 15 19:06:20 2011 +0000

    Don't start the Call when the streams start
    
    Since that can happen before the call is accepted. Instead of that,
    wait for the Call state to be ACCEPTED.
