ChatGpt does not have conversation memory when using access_token only

[yxjiang]

We use https://github.com/acheong08/ChatGPT for ChatGPT communication.

The session_token approach does not work anymore and then we switch to use access_token. Without additionally setting the parent_id and conversation_id, the ChatGPT conversation does not have memory.

The bug has been discussed in acheong08/ChatGPT#1236 (comment).
