Chef::Formatters::ErrorInspectors::CookbookResolveErrorInspector#extract_412_error_message

In my tests, the error from the server is double JSON encoded, but we
should not rely on this not getting fixed.

Return *should* be a Hash like this:
  { "non_existent_cookbooks"     => ["nope"],
    "cookbooks_with_no_versions" => [],
    "message" => "Run list contains invalid items: no such cookbook nope."}
