UI - DISABLE_CACHE=true is required when launching UI for changes made to the assistant to take effect

[sangee2004]

gptscript version v0.0.0-dev+160a7334

Steps to reproduce the problem:

1. Launch UI - GATEWAY_URL=https://gateway-api.gptscript.ai gptscript --ui --disable-cache
2. Create an assistant.
3. Edit this assistant and add a tool.
4. Restating the script or running the script from Home page does not result in changes being picked unless DISABLE_CACHE=true is used when launching UI.
