[mythtv] Duplicated system event REC_STARTED

[Bryan Mayland]

I've noticed that the REC_STARTED system event is sent twice.  This 
causes problems for scripts which expect one STARTED/FINISHED pair and 
not STARTED/STARTED/FINISHED.

programs/mythbackend/scheduler.cpp:Scheduler::RunScheduler()
             if (is_rec)
             {
                 UpdateNextRecord();
                 SendMythSystemEvent(QString("REC_STARTED CARDID %1 
CHANID %2 "
                                     "STARTTIME 
%3").arg(nextRecording->cardid)
                                     .arg(nextRecording->chanid)
                                     .arg(nextRecording->recstartts
                                                       
.toString(Qt::ISODate)));
             }

libs/libmythtv/tv_rec.cpp:TVRec::StartedRecording()
              SendMythSystemRecEvent("REC_STARTED", curRec);

I do not believe the first should be there.  SendMythSystemRecEvent() 
calls SendMythSystemEvent() with the exact same parameters, so I assume 
the duplication is an oversight and the REC_STARTED event should only 
fly once the TVRec actually starts recording, not when the Scheduler 
wants to start a recording.

Does this need a ticket?
