When the message sent to the ai is empty, like how folks will use /schema, we receive an error: `unhandled status from server, please report the following request id`
This only happens in non-insiders VSCode.
It might be fixed in insiders, but since we do want to release the extension now we should work around it. We can add a not-empty message in those cases so it doesn't error, and skip any meta-data model requests since they'd be erroring without user input.
