If you do preview of project for first time on both ios and android devices, the command crashes with
TypeError: Cannot read property 'hash' of null
at PreviewAppController. (C:\Users\test\AppData\Roaming\npm\node_modules\nativescript\lib\controllers\preview-app-controller.js:130:64)

at process._tickCallback (internal/process/next_tick.js:68:7)

To Reproduce

1. tns create TestApp --js
2. tns preview
3. Scan the QR code on android and then scan it on ios device. Preview command crashes.
   On next preview runs everything works as expected

Other way to reproduce the same error is: tns preview, scan the qr code on some device and then make change in project's package.json file.
