"start chatting" on assistant landing is ignored for new users

[nsarrazin]

Bug description

When a new user (new session id) lands on huggingchat for the first time, if the page is an assistant landing page and they click "start chatting" they get redirected to the default landing page with the default model

Steps to reproduce

1. open a new private window tab
2. go to the landing page of any assistant (https://huggingface.co/chat/assistant/66dacdafbb1b88ad80e130d9)
3. press "start chatting"
4. get redirect to chat with llama 3.1 70b instead of a chat with the assistant
5. If you do it again it will work, it only fails for the first landing

Config

HuggingChat in prod

Notes

Probably due to the initialization of settings when the user gets the welcome modal which means the setting of the assistant is ignored? this is quite important since being able to share assistants with anonymous users is an important feature of huggingchat

Thanks for posting. In Safari, I believe the bug persists despite refreshing the page.
