Cleanup: Remove the ai-logs flag. (#679)

* This flag is deprecated and no longer used.
* The frontend should have stopped using this flag starting in 3.7.5
* The frontend is now up to 3.8.5
* So we should be good to remove this flag because the frontend should
no longer be setting it.

* Related to jlewi/foyle#211
