Leak of dispose after sound stop

[nishimura-ryouta-ftd]

Nice to meet you. I found a simple leak.

After calling stop() , There is a reference left to _counterNode

The cause is simple.

dispose function

        if (this.isPlaying()) {
          try {
            this._counterNode.stop(now);
          } catch (e) {
            console.log(e);
          }

          this._counterNode = null;
        }

When Call dispose() after stop(), the reference of _counterContainer remains. so I try this code. Leaks no longer occur.

        if (this.isPlaying()) {
          try {
            this._counterNode.stop(now);
          } catch (e) {
            console.log(e);
          }
        }
        this._counterNode = null;

Are you aware of the negative things of this change?
