Hello,

I'm working on a website in Sylius 1.6 with one locale (mywebsite.com/fr_FR), and I want to add Facebook login.
If I put the path `/login`, Facebook will redirect to mywebsite.com/login which fail (blank page with only a link to facebook).
But if I put the route name, the path will be `/fr_FR/login`, which works fine (for me at least)
