Cleanup: Head title shouldn't have a special case for views.

Problem/Motivation

template_preprocess_html contains:

  // @todo Remove once views is not bypassing the view subscriber anymore.
  //   @see https://www.drupal.org/node/2068471
  elseif ($is_front_page) {
    $head_title = [
      'title' => t('Home'),
      'name' => $site_config->get('name'),
    ];
  }

That issue was closed. So we should be safe to remove that special case.

Proposed resolution

We probably need a test ensuring this. The test should create a view, set it as the home, and ensure the title is Home and not the views title.

Remaining tasks

Patch removing that code, test.
