Describe the bug
As in the title

To Reproduce
Steps to reproduce the behavior:

1. Set up two languages in Starterkit and assign a language-specific URL to each
2. In config, set languages to true and languages.detect to false (should be the default, anyway)
3. Try to open non-default domain in a browser
4. See it redirecting to the default domain (Chrome network tab shows a 302 redirect)

Expected behavior
Needless to say that no redirect should happen unless language detection is active.
