Scenario: Files Delete
  Given I have no files
  When I upload the file at "features/uploads/refinery_is_awesome.txt"
  And I go to the list of files
  And I follow "Remove this file forever"
  Then I should have 0 file
  # next line fails ...
  # And I should see "'refinery_is_awesome.txt' was successfully destroyed."
