[TIMOB-23279] Only report a device when one has been detected

[garymathews]

• If a device has not been detected then no devices should be reported
• Skip any invalid devices detected by wptool (such as two devices at once, which is unsupported)
• Use wptool with 8.1 and 10.0 but not 8.0 (which is now unsupported)

I still see following device that doesn't have udid. It's supposed to be removed, right?

    {
      "name": "Device",
      "udid": 0,
      "index": 0,
      "wpsdk": null
    },

test code

windowslib.device.detect(function (err, results) {
    console.log(JSON.stringify(results,null,2));
});

result

{
  "devices": [
    {
      "name": "Device",
      "udid": 0,
      "index": 0,
      "wpsdk": null
    },
    {
      "name": "Windows 10 Mobile Device",
      "udid": "00000015-cxxf-8a24-0000-000000000000",
      "index": 0,
      "wpsdk": null,
      "ip": "127.0.0.1"
    },
    {
      "name": "Lumia 630 Dual SIM (RM-978)",
      "udid": "00000015-4xx1-3x2b-0000-000000000000",
      "index": 1,
      "wpsdk": null,
      "ip": "127.0.0.1"
    }
  ],
  "issues": []
}

Yes, that's correct. Currently, it will always detect that placeholder device. Even when no devices are plugged in. So removing it would correctly report that no devices are connected.
