refactor(routes): Rename indexRoute and loadIndexRoute (ngrx#93)

BREAKING CHANGE:

  `indexRoute` is now `index` and `loadIndexRoute` is now `loadIndex`

  BEFORE:

  ```ts
  const routes: Routes = [
    {
      path: '/',
      component: MarketingTemplateComponent,
      indexRoute: {
        component: HomePageComponent,
      }
    },
    {
      path: '/blog',
      component: BlogComponent,
      loadIndexRoute: () => System.import('app/routes/blog')
    }
  ];
  ```

  AFTER:

  ```ts
  const routes: Routes = [
    {
      path: '/',
      component: MarketingTemplateComponent,
      index: {
        component: HomePageComponent
      }
    },
    {
      path: '/blog',
      component: BlogComponent,
      loadIndex: () => System.import('app/routes/blog')
    }
  ];
  ```
