    Fix AMI action Park crash.
    
    * Made AMI action Park not say anything to the parker channel (AMI header
    Channel2) since the AMI action is a third party parking the call.  (This
    is a change in behavior that cannot be preserved without a lot of effort.)
    
    * Made not play pbx-parkingfailed if the Park 's' option is used.
