Make AMI event AgentCalled get CallerID/ConnectedLine info from the incoming channel.

Make AMI event AgentCalled get CallerID/ConnectedLine info from the incoming channel.

It was strange that the AgentCalled AMI event would get most of its
information from the incoming channel but then get the CallerID
information from the outgoing channel.  Before connected line support was
added, this information was always the same at this point.
