title: Angular router include extra segment to the path when useHash is enabled
body: <p>I have an angular application deployed under an URL looks like this:</p>
  <p><code>https://example.com/my-angular-application</code></p>
  <p>This is a requirement in my project to use hash routing so I set <code>useHash: true</code></p>
  <p>In case if I start the application and my default route is <code>/abcd</code> I would expect the URL to look like this:</p>
  <p><code>https://example.com/my-angular-application/#/abcd</code></p>
  <p>But instead of this I got:</p>
  <p><code>https://example.com/my-angular-application/#/my-angular-application/abcd</code></p>
  <p>What can cause this behaviour?</p>
  <p>I've tried to use redirect to resolve this but it did not help.</p>
