The redirect URL is wrong

```ruby
  @no_login_redirect = { controller: '/session', action: 'new' }
```

The controller name should be sessions, not session.
Not positive this is where the test belongs, but the alternative is to test all of the configuration class which is only being touched by other tests, as here.

Since we're obviously not testing what we wanted, perhaps that's a good idea, but I think it could be done in a different commit.
