Fix SSL EV Plus duplication issue

[abunashir]

Currently, the duplication for SSL EV Plus request throws an Invalid DNS name issue. After looking into this we found this interface does not expect us to provide both root and www in the same request, otherwise it won't process that request.

This commit adds simple fix, and it will remove www. from the dns_names list and this should fix the issue for now.

Fixes: #135

@kwkwan could you help check if this solves the problem? Thanks!

As the certificate is EV SSL certificate, we should select dns_name starts with “www.” instead of removing it.

dns_names.select{|dns_name| dns_name.match(/^(www.)/) }

Otherwise, it will cause error

order = Digicert::OrderDuplicator.create(order_id: order_id)
Digicert::Errors::RequestError: [{"code"=>"invalid_dns_name_on_duplicate", "message"=>"Invalid DNS name on duplicate request. The DNS names must match what was on the original order."}]

@kwkwan I'm not sure about the complete scenario for other types of duplication or reissue, but I've modified the regex a bit so it selects any subdomains except the root domains, and please let me know if that fixes the issues. Thanks!

@kwkwan: Merging it for now, but please check it out whenever you have a chance and if necessary then I will add the necessary changes, Thanks!
