In case of polyfill, `reviver` function should be called in the `holder` context

[zloirock]

Now it does not work with this polyfill, however, it's one of the key moments of ES JSON implementation:

JSON.parse('{"a":1}', function (key, val) { this.b = 2; return val; }); // => { a: 1, b: 2}

Like in #4, for implementing this, JSON should be parsed before calling reviver function.
