Fix connection leaks: Ensure that any pending connection open are cancelled/undo when ActiveCall is unmounted (#3255)

* Better logs for connection/component lifecycle

* fix: `AudioCaptureOptions` was causing un-necessary effect render

AudioCaptureOptions was a different object but with same internal values, use directly deviceId so that Object.is works properly

* fix: Livekit openned connection leaks

* review: rename to AbortHandles

* review: rename variable
