react/wrap-multilines conflicts with no-extra-parens

Imo we should wrap multiline JSX with parens to keep the mark-up balanced, e.g.

```
return (
    <div>
        <h1>Hello world</h1>
    </div>
);
```

But in addition it's nice to error when extraneous parens are used elsewhere. We need to work out how we can have best of both.
