replica-manage: Properly delete nested entries
    
    Bad ordering of LDAP entries during replica removal resulted in a failure to
    delete replica and its services from cn=masters,cn=ipa,cn=etc,$SUFFIX. This
    patch enforces the correct ordering of entries resulting in proper removal of
    services before the host entry itself.
