Issue with FaceRecognition subscription in "Roar" #5
Description
When running the code for the "Roar" sample, Misty returns a value of undefined for the data.message.distance property on line 50. It looks like no distance value is getting returned in the data object returned by the first message sent by the subscription. I think we need to incorporate a conditional statement so that Misty does not react when the initial "successful subscription" message is sent, and instead Misty waits for a real face rec event that contains meaningful data.
