Fix script file upload from *formidable* migration (#1950)

* Retested lib and userscript on dev

Post #1949

NOTE:
* *formidable* can't easily be "poor mans debugged" via `console.log(script)`. Must use `JSON.stringify(script)` to avoid throw
* Ref https://github.com/node-formidable/formidable/blob/2815e914a6d2465e5fa1c52f09c1dcd77a544659/README.md#file
