Subject: [PATCH] Failing test for fbt issue

Specifically, the fbt plugin would error on a `null` loc as it [relies on it in
one of its
utils](https://github.com/facebook/fbt/blob/6a23a5374a757a49654d8304a3efea8eb9548eea/packages/babel-plugin-fbt/src/getNamespacedArgs.js#L82-L84),
implying a missing `loc` somewhere in our pipeline after codegen
