Broken "group" links under access management when using custom domain (BB-8957)

For a given page with a custom domain, such as http://code.mydomain.com/myrepository/admin/access, the "group" links point to http://code.mydomain.com/account/user/myuser/groups/#group:developers etc, which does not exist. It should point to https://bitbucket.org/account/user/myuser/groups/, or some other equivalent management page under the custom domain that I am not aware of.
