Default build (not prod) returns __chunk1_js.default$7 is not a function error

```
evergreen.js:25 Uncaught TypeError: __chunk1_js.default$7 is not a function
at evergreen.js:25
at __babelPolyfillDefine (shared.js:10)
at evergreen.js:1
```

This seems to happen when my evergreen and targets don't match. Notice `'last 1 Edge versions'` missing in targets.

Using the following config:

```js
'ember-cli-babel-polyfills': {
evergreenTargets: [
'last 1 Chrome versions',
'last 1 Firefox versions',
'last 1 Safari versions',
'last 1 Edge versions'
],
},
```

And targets:

```js
'use strict';

const browsers = [
'last 1 Chrome versions',
'last 1 Firefox versions',
'last 1 Safari versions'
];

const isCI = !!process.env.CI;
const isProduction = process.env.EMBER_ENV === 'production';

if (isCI || isProduction) {
browsers.push('ie 11');
}

module.exports = {
browsers
};
```
