Migration from 2.0.2 to 2.0.3: default rule in portal vhost is now applied
When upgrading LL::NG from 2.0.2 to 2.0.3, when there are already rules on portal vhost, a default rule is added with value 'unprotect', which breaks the portal (anonymous access).
We should set the default rule to 'accept'.
