Fix reverse zone creation in ipa-replica-prepare
When a new reverse zone was created in ipa-replica-prepare (this may happen when a new replica is from different subnet), the master DNS address was corrupted by invalid A/AAAA record. This caused problems for example in installing replica. https://fedorahosted.org/freeipa/ticket/1223
