Do not error out when a network is ipv6 only

Currently with the following network definition in network-data:

- name: InternalApi
  name_lower: internal_api
  mtu: 1500
  vip: true
  ipv6: true
  subnets:
    internal_api_subnet:
      ipv6_subnet: fd00:fd00:fd00:1000::/64
      ipv6_allocation_pools:
        - start: fd00:fd00:fd00:1000::50
            end: fd00:fd00:fd00:1000::90

We fail as follows:
 Error rendering template /home/stack/overcloud-deploy/overcloud/tripleo-heat-templates/network/internal_api.yaml : 'dict object' has no attribute 'ip_subnet'
 Traceback (most recent call last):

     {%-     if ":" in network.subnets[subnet]['ip_subnet'] or network.ipv6|default(false) or ipv6_override %}

We need to put the """if ":" in network.subnets[subnet]['ip_subnet']"""
check after the ipv6 test. After applying this patch I was able to
correctly deploy the overcloud.
