adding a child page without a default translation cannot be edited in the backend

[jess]

here's a failing test: b446ee9

I fails because @page is nil. The find_by_path_or_id method returns nil because the path is parent-page/5 instead of just the id or slug, ie 5

   69: def find_page
=> 70:   binding.pry
   71:   @page = Refinery::Page.find_by_path_or_id(params[:path], params[:id])
   72: end

[1] pry(#<Refinery::Admin::PagesController>)> params
=> {"switch_locale"=>"ru",
 "controller"=>"refinery/admin/pages",
 "action"=>"edit",
 "path"=>"parent-page/5",
 "locale"=>:en}

[2] pry(#<Refinery::Admin::PagesController>)>          Refinery::Page.find_by_path_or_id(params[:path], params[:id])

=> nil

Should be fixed by #2379.
