Subject: Fixes URL generation with trailing_slash: true

URL generation with trailing_slash: true was adding a trailing slash
after .:format

    Routes.draw do
      resources :bars
    end

    bars_url(trailing_slash: true, format: 'json')
      # => /bars.json/

This commit removes that extra trailing slash
