Update from Phoenix 1.4.9 to 1.4.17 -> Router.Helpers Problem

The _build removal did not fix it.

My web.ex looks like the following:

  def controller do
    quote do
      use Phoenix.Controller

      alias MyApp.Repo
      import Ecto
      import Ecto.Query

      import Bodyguard

      import MyApp.Router.Helpers
      import MyApp.Gettext
    end
  end

and then controllers look like the following:

defmodule MyApp.XYController do
  use MyApp.Web, :controller

The router uses that:

defmodule MyApp.Router do
  use MyApp.Web, :router

To me it looks like the module has been renamed or moved or whatever?
