Bug Description
At the moment when an application that started the camera stops becoming active, the camera remains running and other applications can't use it.
The system should automatically detect when an app is being deactivate and stop the camera, as a minimum.
To be symmetric, when the app gets activated again, it should also restart it. However this might not be as simple since the camera might have been re-configured by other apps so if we want the process to be full automatic the state of the camera configuration should be saved and restored as well.

This can be reproduced by opening uTorch, leaving it open and then open the camera-app. The camera app will be broken.
