feat: update to Angular 8

The main noticeable change in the removal of `@nguniversal/module-map-ngfactory-loader`. This is because now in Angular 8 we support standard import syntax which no longer require custom logic to support lazy loading.

Example
```ts
loadChildren: () => import('./lazy/lazy.module').then(m => m.LazyModule)
```

instead of
```ts
loadChildren: './lazy/lazy.module#LazyModule'
```
