Task confirmation test

Hi !

Please find my work for the task confirmation test for vreasy.

Best Regards. 


@brutuscat the Twilio API states that when you send the SMS, you make an asynchronous call that insert you're send request in a queue.
We could just leave it at that but we wouldn't know if the SMS was successfully sent. If we want to be sure of it, we can create an endpoint on our side that Twilio will call to notify us and then use this response to update the task status on our side. We just need to add this URL in the StatusCallback parameter with our sending request to Twilio.
