Regenerator Runtime is not defined with no configuration

Hey, Im still getting a "ReferenceError regenerator runtimes is not defined" when using backpack out of the box. Im not specifying any custom `.babelrc` or `backpack.config.js` files and im simply trying to use an `async/await` function in my `src/index.js` file but with no luck Any ideas on why it wouldn't be working?

```javascript
async function foo() {
await Product.find({_id: 1});
}
```

Start with src/index.js and reproduce the reported async/await example using Backpack's default configuration. Read the generated build and default Babel-related configuration to determine why the regenerator runtime is unavailable; done means the example runs without a custom .babelrc or backpack.config.js.
