captureVideo doesn't close camera picker and doesn't show alert message about prohibited camera usage

Steps to reproduce:

1. Create a simple application which calls `captureVideo()` method
2. Deploy application to real device
3. Click on button which starts video capturing
4. Click "No" when it asks permissions for camera

Expected result:
camera picker is animated out. And every time when user clicks on capture video alert is shown as in `cordova-plugin-camera`: Access to the camera has been prohibited, please enable it in the Settings app to continue. And 2 buttons are shown: OK, Settings

Actual result:
camera picker is not hidden. It's possible to click on record button and record black screen. Eventually video is saved and viewed
