It's possible to create a site in Site Factory without any public access, which breaks the admin panel.

Setup:
Use setup from https://github.com/ezsystems/ezplatform-ee/pull/130

*Steps to reproduce:
1. Login as admin
2. Go to "Site" > Site Factory (click the icon)
3. Click "Create"
4. Enter the Site name and select layout "RoadShow"
5. In the access enter:
Access: {{test.local}
Language: English
6. Create the Site
7. In the Site details click the link in "access" column: test.local

Expected:
I'm redirected to test.local and can preview my page on frontend.

Actual:
I'm redirected to http://example.com/admin/site/test.local, a route which does not exist.
