Steps to reproduce:

1. Start a latest master bundle
2. Create a site
3. Create two pages, called Home and Test Page
4. Go to the site's configuration, set a virtual host for public pages e.g. www.test.com
5. Access the Test Page with the virtual host URL (www.test.com:8080/test-page)
6. Search for the block that contains "hreflang="en-US", verify that "/en" is not appended to the alternate URL of "en-US".
   Result:

   <link data-senna-track="temporary" 
   href="http&#x3a;&#x2f;&#x2f;www&#x2e;test&#x2e;com&#x3a;8080&#x2f;test-page" 
   hreflang="en-US" rel="alternate" />
   

1. Access Home page with the virtual host URL (www.test.com:8080)
2. Search for the block that contains "hreflang="en-US"
   Result:

    <link data-senna-track="temporary" 
   href="http&#x3a;&#x2f;&#x2f;www&#x2e;test&#x2e;com&#x3a;8080&#x2f;en" 
   hreflang="en-US" rel="alternate" />
   

Actual behavior: "/en" is appended at the home page

Expected behavior: "/en" is not appended at the home page
