Print takes the node raw if exists
https://github.com/Rich-Harris/code-red/blob/master/src/print/handlers.js#L1423 else the value and after updating the code-red from "0.1.4" to "0.2.1" this update got missed.

Thanks for the investigation and the fix! I've made a couple of small changes to this - one is to not rewrite the path unless we actually have to - and the other is to simply clear the raw and leave code-red to be responsible for running JSON.stringify on the value.

Thanks for the refactoring 👍 I follow these patterns next time.
