Camera test failure

[Víctor R. Ruiz]

On Ubuntu Touch image 20130918.1:

Test case:
- adb shell
- su - phablet
- cordova-ubuntu-2.8 --desktop_file_hint=/usr/share/applications/unity8.desktop /usr/share/cordova-ubuntu-tests/cordovamobilespec/www/
- Click on Camera.
- Click on camera.getPicture().

Expected results:
- A similar window to the camera-app must be displayed.
- Clicking on the "capture" button must return the image to the application.

Actual result:
- No live view in the "capture" mode.
- The only way to return is to click on the "return" button on the live view.
- No image is captured. "NaN. Error getting picture: undefined".
