toString() for node objects

[manuelschneider]

Currently lib/zone.ts on line 1166 states:

    public toString() {
      if (this.data && typeof this.data.handleId !== 'undefined') {
        return this.data.handleId;
      } else {
        return Object.prototype.toString.call(this);
      }
    }

Shouldn't this be

      if (this.data && typeof this.data.handleId === 'number') {

? Because otherwise it returns node timer objects, which are not strings.

Close for fixed.
