[FEATURE]2.0.3版本的JSONObject.parseObject方法在指定了Feature.OrderedField的时候也不能保序

[qsmmeng]

测试用例：

    public static void main(String[] args) {

        String a = "{\"resultCode\":\"200013\",\"message\":\"查询成功\",\"data\":{\"clientName\":\"张三\",\"clientId\":\"3002674743\",\"phoneNumber\":\"13412345678\",\"gender\":2,\"age\":59}}";

        JSONObject jsonObject = JSONObject.parseObject(a, Feature.OrderedField);

        System.out.println(jsonObject);

    }

2.0.3版本输出如下：

{"data":{"clientId":"3002674743","phoneNumber":"13412345678","gender":2,"clientName":"张三","age":59},"resultCode":"200013","message":"查询成功"}

1.2.83版本输出如下：

{"resultCode":"200013","message":"查询成功","data":{"clientName":"张三","clientId":"3002674743","phoneNumber":"13412345678","gender":2,"age":59}}
