setLocale() doesn't change the language set by browser

@eelisland I think you can move the following code to Event pre_system.

PHP Code:

        if (session()->has('locale'))
        {
            // Set site language to session locale value
            service('language')->setLocale(session('locale'));
        }
        else
        {
            // Save locale to session
            session()->set('locale', service('language')->getLocale());
        }
