NPE in sort-reqs

[agriffis]

This is similar to an issue previously reported at #310 (comment)

(ns foo (:require [a.b.c :refer []]))

This fails for me with

When :list called an option-fn named 'sort-reqs' it failed because: java.lang.NullPointerException

I don't know what :refer [] means here. Blame my coworker. But the formatter probably shouldn't fail. 😂

zprint 1.2.9

Thank you very much! The formatter certainly shouldn't fail, and I can reproduce it. I will fix it in the next release. It isn't a trivial fix because the code that rewrites things (as in sorting them) is rather complex.
