Does not return proper accessToken

Sqlite3 connector gives following when logging in:
Access token stored in the database is correct, but returned id is the id of accessToken instead of the token itself.

{
  "id": 1,
  "ttl": 1209600,
  "created": "2016-02-22T13:32:31.305Z",
  "userId": 1
}

When using db(in-memory) for storing access tokens it gives following correct result.

{
  "id": "APXMEsHyWmZmXBgi5vAMfWwVfd72nyaXCihskDvqvQILjoliSfGRlcS9MDrtkrrR",
  "ttl": 1209600,
  "created": "2016-02-22T13:33:41.987Z",
  "userId": 1
}

使用 SQLite3 connector 重现一次登录，并将其返回的 access-token 对象与 issue 中显示的正确 in-memory 结果进行比较。跟踪存储的 access token 如何被读取和返回；完成的标准是 SQLite3 响应将 token 字符串作为 id 暴露，同时保留 ttl、created 和 userId。
