Fix for Rails locales when testing with Rspec, Capybara etc...

routing_helper.rb

# spec/support/routing_helper.rb

class ActionDispatch::Routing::RouteSet::NamedRouteCollection::UrlHelper
  def call(t, args)
    t.url_for(handle_positional_args(t, args, { locale: nil }.merge( @options ), @segment_keys))
  end
end

Failure/Error:
       def call(t, args)
         t.url_for(handle_positional_args(t, args, { locale: nil }.merge( @options ), @segment_keys))

     ArgumentError:
       wrong number of arguments (3 for 2)
