Compability with SensorUp demo server #9

It seems that sensorthing-datasource has issues with https://toronto-bike-snapshot.sensorup.com/v1.0.

The problem is only with Location data. Other data (from 2017) can be queried.

Looks like the query has an issue. It only selects time from the parent object: https://toronto-bike-snapshot.sensorup.com/v1.0/Things(206047)/HistoricalLocations?&$expand=Locations($select=name,location)&$select=time&$top=1

{
  "@iot.count": 1,
  "value": [
    {
      "time": "2017-02-04T15:50:10.489Z"
    }
  ]
}

Without selector: https://toronto-bike-snapshot.sensorup.com/v1.0/Things(206047)/HistoricalLocations?&$expand=Locations($select=name,location)&$top=1

{
  "@iot.count": 1,
  "value": [
    {
      "@iot.id": 206049,
      "@iot.selfLink": "https://toronto-bike-snapshot.sensorup.com/v1.0/HistoricalLocations(206049)",
      "time": "2017-02-04T15:50:10.489Z",
      "Locations": [
        {
          "name": "7061:Bloor St / Brunswick Ave",
          "location": {
            "coordinates": [
              -79.407224,
              43.665876
            ],
            "type": "Point"
          }
        }
      ],
      "Thing@iot.navigationLink": "https://toronto-bike-snapshot.sensorup.com/v1.0/HistoricalLocations(206049)/Thing"
    }
  ]
}
