'continuous' doesn't stop when granite-qrcode-scanner is disconnected

[davidmaxwaterman]

If the element with continuous set is disconnected, some internals of the scanner aren't stopped, and there is continuous console output.

I suggest adding a disconnectedCallback() to set the active and continuous options to false - that seems to work in my experiments, but perhaps there's a 'better' way if you have more knowledge of the internals. For now, I can add these to the disconnectedCallback() in my element (since it is also removed).

Going to look at that, thanks :)

Is this issue resolved?
I think, in order to switch off the camera, the stream should be closed.
stream.getTracks().forEach( t=> { t.stop(); });

I'm not able to look at this in the foreseeable future.
