Error if the cwd is not the root of the package that is transpiled with babel

This might be a very rare edge case, but I'd like to seet his fixed (a PR is on its way) and discuss this.

I have a react-styleguidist setup where I join multiple styleguides into one big styleguide. Each project (each individual style guide) uses babel and babel-plugin-direct-import. The problem is that when I build my big styleguide, babel does run from there and process.cwd() is not the root of every individual component anymore. This causes babel-plugin-direct-import not to find dependencies that are only used by individual components.

Long story short: process.cwd() not being the path of the module that uses babel-plugin-direct-import breaks it.

Good point, I was thinking about injecting cwd at the beginning (https://github.com/lodash/babel-plugin-lodash/blob/master/src/config.js#L17), but then decided to make it simpler.

[leMaik]

Yeah, that would make the config syntax more complicated again and would require me to put the cwd into all .babelrc files.
The proposed PR doesn't require config changes. :-)

@leMaik yeah, I wrote it before I saw your PR , lets move our discussion there.
