Fixed a bug with the Break mechanism

The notifier with zero timeout used to acknowledge break messages was executed at the same time as the completion wait for notification in the "Wait for Iteration Notification.vi". This resulted in the fact that break messages, which can happen after the moment in witch the wait on notification started, would be not acknowledged while waiting for the current iteration completion

Now the break notifier is started after the completion notifier has exited this avoiding missing upon break messages during the current iteration
