Fix Queue Log Reporting Every Call COMPLETECALLER With "h" Extension Present

When the "h" extension is present within the context of the queue, all calls
are being reported COMPLETECALLER even when the agent is hanging up the call.

This patch checks to see if the agent hung-up or not instead of only relying on
checking if the queue (caller) channel hung-up or not.  It would appear that
having the h extension in the mix, the pbx goes to the h extension,
"hanging-up" the queue channel and triggering the reporting of COMPLETECALLER.
