Remove unnecessary code after adding uniq in domain parsing

In the previous commit we made sure that we only returned a list of unique
server_names/domains, which is basically what this code did previously.
I also found out that certbot is able to ignore duplicate domain names in
the request made to it, so this code was superfluous to begin with :(
