Upload being cancelled crashed the Node process
I'm implementing an upload form for large files, and everything is dandy except for one particular issue: when the user closes its browser (which cancels the request), the node process crashes.

I've been able to trace the issue to this line: https://github.com/jaydenseric/graphql-upload/blob/master/processRequest.js#L335, and confirmed it by commenting out the code.

Is there a way to prevent the crash I didn't see?
