Stream not closed on component destroy

[saidul]

Possible fix:

       beforeDestroy () {
            const camera = this.$refs.camera
            window.removeEventListener('resize', this.handleWindowResize)
            camera.removeEventListener('play', this.handleOnPlay)
            camera.removeEventListener('pause', this.handleOnPause)

            if (camera.srcObject) {
                let tracks = camera.srcObject.getTracks();
                tracks.forEach(track => {
                    track.stop();
                });
            }
        },
