Handle New Style Reveal Spray Data

[moshthepitt]

So the mSpray data for reveal phase 1 will look like this:

{
    "id": "156729",
    "parent_id": "3537",
    "status": "Active",
    "geometry": "{\"type\":\"Point\",\"coordinates\":[32.6449483606322,-14.1563828768012]}",
    "server_version": 1542970626309,
    "task_id": "2caa810d-d4da-4e67-838b-badb9bd86e06",
    "task_spray_operator": "demoMTI",
    "task_status": "Ready",
    "task_business_status": "Not Visited",
    "task_execution_start_date": "2015-09-21T1000",
    "task_execution_end_date": "2015-09-21T1100",
    "task_server_version": 1543867945196
}

We need to change the code to support this, and add tests.
