Babel on node_modules folder fails when libraries have custom .babelrc

[ethanroday]

Steps to reproduce (on latest master):

1. Run preact create <app-name>
2. cd <app-name>
3. npm install --save redux preact-redux
4. In app.js, initialize a store and hook it up with a <Provider> component
5. npm run build

Expected result:

The build will succeed.

Actual result:

The build fails, since node_modules/preact-redux has a .babelrc file, which references the transform-node-env-inline plugin. Since #117, ES6 code under node_modules gets run through Babel. Babel picks up the .babelrc file in node_modules/preact-redux and fails, since the transform-node-env-inline dependency is not installed.
Installing the plugin (as well as the react and es2015 presets) fixes the problem, but I certainly don't think the expected behavior should be for the build process to npm i in every library folder that contains ES6 code (especially because most of them, preact-redux included, already ship with a precompiled ES5 version). Then again, you can't just assume that the CLI's Babel config will be sufficient for any given library that doesn't ship with ES5 code.
@prateekbh, thoughts?

What version of preact-cli are you using?

Just re-read, sorry - though I wonder if you ended up with an older version in local node_modules?

Hm, I don't think so. I ran a fresh npm i. Why, are you not getting this?

@ethanroday this PR supposes to fix that #153 . It's in preact-cli@1.3.0.

Ah I last pulled yesterday mid-morning PST. Assumed I was on latest master but I wasn't! You guys move so fast!
Can confirm that this particular case is fixed.

Aye, we saw this as an issue right after releasing 1.2.0

Thanks for such detailed reports though!
