Disable Bundler/DuplicatedGem

Bundler/DuplicatedGem will flag this:

if ENV["RAILS_NEXT"]
  gem "rails", "~> 5.1.0"
else
  gem "rails", "~> 5.0.0"
end

Which is in fact a very valid thing to do if you're upgrading rails by using bootboot. I think we should disable this one

But after doing bundle open standard in my local environment, this is what I see:

I see that the false positive has been fixed in rubocop: rubocop/rubocop#8666 -- so this is probably a wrong version issue on my side...
