PBXReferenceProxy missing display_name attribute.

Hello
I noticed that if I open my project and immediately save it without changing anything, the project file was always changes. All the lines like

0D492AD61E6D924B00A313DB /* SDWebImage.framework in Frameworks */ = {isa = PBXBuildFile; fileRef = 0D492AC71E6D91B300A313DB /* SDWebImage.framework */; };

Changed to

0D492AD61E6D924B00A313DB /* ReferenceProxy in Frameworks */ = {isa = PBXBuildFile; fileRef = 0D492AC71E6D91B300A313DB /* SDWebImage.framework */; };

I look like in build_file.rb#L45 it calls the ref display_name which is not implemented there so it fails over to the base implementation, and since name doesn't exist, ReferenceProxy is returned.
I believe adding display_name to PBXReferenceProxy that returns path if name doesn't exist should fix it.

I solved it by opening the class in my code:

module Xcodeproj
  class Project
    module Object
      class PBXReferenceProxy
        def display_name
          return name if name
          return path if path
          super
        end
      end
    end
  end
end
