Re: [mediacapture-main] Camera light and "disabled" tracks

The current text allows applications to work well even if there are no
 stored permissions: if the application disables the track the camera 
light goes out. If the application would have to stop the track to 
accomplish that, the user would have to accept the use of the camera 
once video is desired again.

I think privacy is not an issue with the current spec text, it says 
```When all tracks connected to a source are muted or disabled, the 
"on-air" or "recording" indicator for that source can be turned off```

so if the app briefly enables, takes a picture and then disables the 
UA is allowed (and probably should) to keep the light on a bit longer 
(and should probably keep it lit permanently if this happens more than
 once).

I have greater sympathy for the driver+closing camera issue, but I 
don't think we should make it less appealing for apps without stored 
permission to behave well.
