Deleted chat_id from body

[phpia]

prevent error 400: Unrecognized request argument supplied: chat_id it appears randomly when langfuse pipeline is active

The integration will not work if you delete chat_id from body.

We need to find another way here to be able to identify which inlet matches to the subsequent outlet

[marcklingen]

@tjbck is there an openwebui native id that we can use here? I'd appreciate your guidance on this

[marcklingen]

For context, this is an attempt to fix this issue: langfuse/langfuse#4895

[tjbck]

@marcklingen chat_id should be passed in by default for both inlet, outlet hooks!

[marcklingen]

Thanks @tjbck, I'll attempt a fix here via a new pr

Update, I created this PR which should fix the issue: #388
