    This will crash and left_candidate will never be non-NULL.


Take out that ao2_ref and this is good to go.

> Once a call to start the ice session is made, instead of immediately quitting if the session is already started, we check for a difference in the two candidates lists.  If the lists are identical, we wipe out the new list and keep the old one and just quit then going on with the current ICE session. If the lists are changed, we toss the old list and adopt the new one and restart the ICE session.
