The way localstack is setup makes it hard to test that interactions with it work. This is because the zone to be used is created by the app itself so we don't know what the zone id is from tests. While we can look it up, all tests run in isolation so the same zone is created multiple times.
We should change this to make it testeable. Ideally we would be able to assert that the right records are created/deleted without having to test this on sandbox.
