Using non-existent method name in attributes_table causes infinite loop

[mattvague]

Not sure if this is an Arbre thing or an AA thing, but I accidentally did the following:

ActiveAdmin.register PrintOrder do
  #...
  show do |print_order|
    attributes_table do
      #...
      actions do
        link_to "View PDF", print_order.file_url
      end
    end
  end
end

which causes an insane amount of memory to be used (presumably because there is no such thing as an actions block in attributes_table). Don't have time to look into this more right now but will tomorrow.

If you're using better_errors combined with Ruby 2, you're likely running into #2434 / activeadmin/arbre#16

I can't reproduce this. I get a undefined methodactions' for #ActiveAdmin::Views::Pages::Show:0x007fa1f266e130` exception.
