Issue
Clicking on the Sign In link on the instance virtual host is causing a 404 error when site virtual host is also set.

Steps to Reproduce

1. Set the following 2 addresses to your /etc/hosts file

   127.0.0.1 test.au
   127.0.0.1 www.test.au
   

1. Start a clean 7.2 dxp-5 instance
2. Login as [e-mail]
3. Agree to terms and set the password reminder
4. Go to [Control Panel > Configuration > Virtual Instances]
5. Edit the existing liferay.com virtual instance and save

   virtual host: test.au
   mail: test.au
   

1. Access http://test.au:8080/
2. Click on Sign In link - Assert that the sign in portlet loads successfully
3. Login as [e-mail]
4. Go to [Site > Configuration > Site Settings > Site URL]
5. In "Public Pages", set the host to "www.test.au" and save
6. Sign out
7. Access http://www.test.au:8080/
8. Click on Sign In link - Assert that the sign in portlet loads successfully
9. Close the popup
10. Access http://test.au:8080/
11. Click on "Sign In" link

Actual Behavior
Sign in portlet is blank, and page is automatically reloaded. 404 errors displayed in liferay log:

WARN  [http-nio-8080-exec-8][code_jsp:160] {code="404", msg="/home", uri=/home}

Expected Behavior
Sign in portlet is displayed in the modal window without any issues.

Research
If you set virtual.hosts.default.site.name= (i.e., blank) this allows the modal to load up on both www.test.au and test.au. It appears that it's trying to apply "Guest" site based on the default portal property.
