[version-1.2]事务查询中包含delete data语法，数据异常

[alexgaoyh]

在执行如下单元测试的时候，将查询不到任何数据信息，与返回的信息矛盾，期望的返回信息是应该包含部分三元组数据，如果不执行 updateRes 段落的 delete data ，则数据展示正常 。

    @Test
    public void transaction() throws Exception {
        String transactionDBName = "transaction";
        // 在服务端执行 cd /home/alexgaoyh;  touch gStore-empty.nt 命令，生成一个空的文件，这样就可以进行 DB 创建
        String dbPathInServer = "/home/alexgaoyh/gStore-empty.nt";
        // 事务隔离级别，串行化
        String isoLevel = "3";
        GstoreConnector gc = new GstoreConnector(ip, port, httpType, username, password);

        // 先删除DB，再创建DB
        String dropDB = gc.drop(transactionDBName, false);
        System.out.println(dropDB);
        String buildDB = gc.build(transactionDBName, dbPathInServer);
        System.out.println(buildDB);

        // 使用当前 DB
        gc.load(transactionDBName, null, request_type_get);

        // 开启事务
        String begin = gc.begin(transactionDBName, isoLevel, request_type_get);
        JSONObject beginJson = new JSONObject(begin);
        System.out.println(begin);
        if(beginJson.get("StatusCode").toString().equals("0")) {
            String tId = beginJson.get("TID").toString();

            try {
                // 插入三元组数据
                String insertRes = gc.tquery(transactionDBName, tId, "insert data { " +
                        "<人物/#张三> <好友> <人物/#李四>." +

                        "}", request_type_get);
                System.out.println(insertRes);

                String insert2Res = gc.tquery(transactionDBName, tId, "insert data {\n" +
                        "  <人物/#张三> <性别> \"女\"^^<http://www.w3.org/2001/XMLSchema#String>.\n" +
                        "}", request_type_get);
                System.out.println(insert2Res);

                String updateRes = gc.tquery(transactionDBName, tId, "delete data {\n" +
                        "<人物/#张三> <性别> \"男\"^^<http://www.w3.org/2001/XMLSchema#String>." +
                        "}", request_type_get);
                System.out.println(updateRes);

                String commit = gc.commit(transactionDBName, tId);
                System.out.println(commit);

            } catch (Exception e) {
                String rollback = gc.rollback(transactionDBName, tId);
                System.out.println(rollback);
            }
        }

        String checkpoint = gc.checkpoint(transactionDBName);
        System.out.println(checkpoint);

        String res = gc.query(transactionDBName, format_json, SPARQL_SELECT_ALL, request_type_get);
        System.out.println(res);

    }
