Fix: Don't report 'On your network' on localhost (styleguidist#934)

When explicitly setting the serverHost to 127.0.0.1 or localhost,
urls.lanUrlForTerminal is undefined. It makes no sense to print out
undefined, therefore only show the 'On your network' line when it's
defined.

Changelog: 🚀

👋 **[Support Styleguidist](https://opencollective.com/styleguidist) on Open Collective** 👋

## Breaking changes

### Node 6 is the lowest supported version

Styleguidist doesn’t support Node 4 anymore.

(styleguidist#744 styleguidist#839 by @kohgpat)

### New format of template option

We’re now using [mini-html-webpack-plugin](https://github.com/styleguidist/mini-html-webpack-plugin) and [@vxna/mini-html-webpack-template](https://github.com/vxna/mini-html-webpack-template) instead of [html-webpack-plugin](https://github.com/jantimon/html-webpack-plugin).

This will make things like [adding a favicon](https://react-styleguidist.js.org/docs/cookbook#how-to-add-a-favicon) or fonts from [Google Fonts](https://react-styleguidist.js.org/docs/cookbook#how-to-add-fonts-from-google-fonts) much easier.

If you’re using a custom HTML template, you need to update your style guide config.

```js
// 6.x
module.exports = {
  template: './styleguie/template.html'
}

// 7.x
module.exports = {
  template: {
    // This is just an example, there are many more available options
    favicon: 'https://assets-cdn.github.com/favicon.ico'
  }
}
```

See more [in the docs](https://react-styleguidist.js.org/docs/configuration#template).

### Changed Node API

`server` method now returns an object containing a webpack `Compiler` instance and the Styleguidist server, see examples [in the docs](https://react-styleguidist.js.org/docs/api.html#servercallback).

## New features

### Webpack 4 support

Webpack 3 is still supported too.

(styleguidist#857 by @kontrollanten, styleguidist#900 styleguidist#901 by @rubenmoya)

### Examples are wrapped in React.Fragment

You don’t need to wrap multiple JSX tags in a div anymore.

```jsx
// 6.x
<div>
  <Button primary>Primary button</Button>
  <Button secondary>Secondary button</Button>
</div>

// 7.x
<Button primary>Primary button</Button>
<Button secondary>Secondary button</Button>
```
