Node AsyncLocalStorage destroyed/lost when multer 1.4.4-lts.1 or later is used

I made a simple Express app that demonstrates the problem: https://github.com/C-Saunders/multer-test

[AsyncLocalStorage docs for reference](https://nodejs.org/api/async_context.html#class-asynclocalstorage)

It's possible this is an issue with busboy, rather than multer. I didn't attempt to use different busboy versions because there were breaking changes between the versions used by these versions of multer, but it might be possible to untangle these.
