Fix: node should send array of devices to hub

[afathonih]

While the endpoint requires array of device, the node does not send array. Thus, led to error as follows:

[HTTP] --> POST /device-farm/api/register?type=add
[HTTP] {"adbPort":5037,"systemPort":50128,"sdk":"13","realDevice":false,"name":"sdk_gphone64_arm64","busy":false,"state":"offline","udid":"emulator-5554","platform":"android","deviceType":"emulator","host":"http://a.b.c.d:4724","totalUtilizationTimeMilliSec":21645,"sessionStartTime":0,"userBlocked":false}

The node will crash as it was not expecting error 500.

This PR rectify the issue and added the correct type to the method.
