Two equal cookies cause of subdomain handling

[qstiegler]

On one of our Projects, we´ve got a cookie with the Session ID for the whole domain, so we can also access this id from the subdomains. But if i´m working with $cookies or $cookieStore. It doesn´t look at the domain. So when I change, add or delete another cookie on a subdomain, the function create a duplicate of the Session ID cookie for the subdomain, too.

Please fix this, that if a cookie belongs to another subdomain or like in this case to the main domain, it won´t create a duplicate.

Please provide a reproduction via jsbin, plnkr.co or jsfiddle

This saves us a lot of time. Thanks!
