In the Terraform 0.12 Provider SDK acceptance testing framework, attributes that do not call ResourceData.Set() are no longer automatically ignored during ImportStateVerify testing. Here we opt to always refresh the associate_public_ip_address and ipv6_address_count attributes into the Terraform state. This change is backwards compatible.

This changeset is the bare minimum to ensure the existing acceptance testing is in a better passing state with the Terraform 0.12 Provider SDK, however there are likely many more additional changes required once the ImportStateVerify test step is applied to all acceptance tests for the resource as part of some upcoming technical debt work (#4987).
