4. skin.css and wyeditor.css are missing(404) when I try to create or edit page

i can confirm the bug on production ENV. I don't know yet how to fix it. Any thoughts @parndt?

I found the problem: https://github.com/refinery/refinerycms/blob/master/core/app/views/refinery/admin/_head.html.erb#L9-L12

If i remove the { skip_pipeline: true } option it works in dev and in prod env.
