[EGD-8208] Added stop audio route on async response

We get Token on play, and require it in stop. While we cant
stop sound by title & data set to play. And adding standard
handling causes either totally synchronous calls or requires

Fixed expectation for the same named Response, but meant for bell
Needed so that
- we ring only when needed
- we handle CLIP and RING properly
