"error" event sometimes not triggered when permission denied

### Problem description

When the permission gets denied through the system dialog prompt, an "error" event is properly triggered. However, when the view is created after the permission had been denied, no error will be triggered.

### Expected behavior

An error event should always be trigger when the camera permission is disabled.

### Environment

- Tabris.js version: 2.8.1
- Device: iPad Pro
- OS: iPadOS 13.1

### Code snippet

See the plugin example.
