Auto import uses camel case for lowercased filenames instead of pascal case which is against airbnb guidelines

Steps to Reproduce:

1. Create a file called 'airbnb-style-guide.js` with the following content -

const AirbnbStyleGuide = {
  es6: {
  },
};

export default AirbnbStyleGuide;

2. Create a second file and start typing "Air" and notice auto complete.

EXPECTING: import AirbnbStyleGuide from './airbnb-style-guide.js
ACTUAL: import airbnbStyleGuide from "./airbnb-style-guide";

https://github.com/airbnb/javascript#naming--PascalCase-singleton

I'm guessing this is filename guessing since a file called AirbnbStyleGuide.js works correctly.

Reproduces without extensions: Yes/No
