【报Bug】调用官方提供的联系人jar获取方法, 在大量联系人存在的情况下(20K左右), 报空指针异常

示例代码：

plus.contacts.getAddressBook(plus.contacts.ADDRESSBOOK_PHONE, book => {    
      // 可通过addressbook进行通讯录操作    
      book.find(contactFields, list => {    
        const queryFinishTime = new Date().getTime();    
        const rst = dealData(list);    
        const now = new Date().getTime();    
        logger.info(`Query contact finish! count: ${rst.length}, ` +    
          `query cost: ${queryFinishTime - startTime}, ` +    
          `deal cost: ${now - queryFinishTime}ms, ` +    
          `total cost: ${now - startTime}ms`);    
        resolve(rst);    
      }, (e) => {    
        logger.error("Failed to get contacts:" + e.message);    
        resolve([]);    
      }, findOpts)    
    }, e => {    
      logger.error("Failed to get address book: " + e.message);    
      resolve([])    
    });

操作步骤：

前置条件:

1. 调用代码示例中的获取联系人的方法
2. 手机中联系人数量在20k左右
3. 机型为: Samsung Galaxy S22 Ultra，Android 14

在上述条件下, 调用获取联系人, 发现非常慢; 而且出现了空指针异常

预期结果：

能够正常获取到联系人信息

实际结果：

APP崩溃, crash日志如下:
