aborts due to changes to yarn.lock that it introduces itself #110

...aborting

The project I'm building (https://github.com/hopglass/hopglass/) provides a yarn.lock that I use to build it. Apparently yarn2nix changes yarn.lock and then complains about the changes. Example code: https://gist.githubusercontent.com/tokudan/55be884cf1f274dbeae3098f5afab062/raw/9a7ff0cc84051f568adcdb890500ab7777710b45/hopglass.nix

Bump, same thing.

Apparently, the reason is in the code. https://github.com/moretea/yarn2nix/blob/9e7279edde2a4e0f5ec04c53f5cd64440a27a1ae/bin/yarn2nix.js#L71-L77

So, when you're building, yarn2nix tries to change the lockfile, but fails and aborts, as it's run with --no-patch flag. The workaround is running yarn2nix --no-nix to patch it before building (the flag is just to avoid unnecessary config spam, unless you're up to write yarn.nix).
