Barcode Scanner Overlay is not hidden when permission is denied

[rachitbhasin]

Description: When using the BarcodeScannerLivestreamOverlayComponent and camera access is blocked the overlay is not hidden or no event is provided to handle the "ERROR Error: Uncaught (in promise): NotAllowedError: Permission denied".

Steps to reproduce:

1. Navigate to barcode scanner with overlay demo page (link)
2. Click "Scan codebar with overlay window" button.
3. When prompted to grant permission for camera access, click "Block".

Actual result:

1. Camera does not open (as expected), but the overlay does not go away (not desired).
2. Error visible in developer console "ERROR Error: Uncaught (in promise): NotAllowedError: Permission denied"

Expected result:

1. Either overlay should be hidden or an event should be provided to handle the error.
