title: Angular 2 is removing UTM from URL
body: <p>I'm doing work on a site developed with Angular 2. I'm trying to set up UTM campaigns for this site, and I'm running into an issue where the UTM query gets removed from the URL upon page load. This site uses <code>useHash</code> in the <code>RouterModule</code>, so the URL has the following format: <a href="https://examplesite.com/#/home" rel="nofollow noreferrer">https://examplesite.com/#/home</a>.
  When I generate the UTM, I get the following: <a href="http://examplesite.com/?utm_source=newsletter&amp;utm_medium=email&amp;utm_campaign=test_campaign10#/home" rel="nofollow noreferrer">http://examplesite.com/?utm_source=newsletter&amp;utm_medium=email&amp;utm_campaign=test_campaign10#/home</a>.
  When I visit this UTM link, the UTM gets removed...Does this have something to do with <code>useHash</code>? Thanks.</p>
  
  <pre><code>import { Routes } from '@angular/router';
  import { NoContentComponent } from './no-content';
  import { HomeComponent } from '../pages/home';
  
  export const ROUTES: Routes = [
      { path: 'home', component: HomeComponent },
      { path: '**', component: NoContentComponent },
  ];
  </code></pre>
