Fix capture graph listener count: count all cases where the capture graph is needed.

Browse source 
Fix avoiding to have a call and a graph both:
- If in call or new call, switch off the capture graph and to not create new graphs.
- If not in call or no more call, switch on the capture graph if needed (listener count > 0).
- Return volume result to GUI from the capture graph or the current call.
