Panic Output

Expected Behavior

On error from the API terraform bails out and doesn't create the record

Actual Behavior

Terraform created the record, even though there was an error, but doesn't see that it's been created so attempts to create it again on further applys, and can't destroy the record.

Steps to Reproduce

1. Create a malformed SOA record, e.g. it's missing MNAME and / or RNAME
2. terraform apply with the above config, record is created
3. terraform apply or terraform plan attempts to create the record again, even though it's in the statefile
4. terraform destroy removes state, but doesn't remove the record

Important Factoids

Malformed SOA record was created by PowerAdmin, likely down to a configuration fault on my end. However outside of using the API DNS lookups are / were working fine.

Fixing the SOA record resolves the issue.
