DisplayName not retreived by default from latest React APIs

```js
function Foo() {
  return <div />
}

export default React.memo(Foo);
```

Results in:
```
<[object Object] />
```

See https://github.com/facebook/react/issues/14319

Opening an issue here to track the progress, and see what we can do.  
The thing is we need the displayName not only for DEV env, but also production.
