Regressions were introduced when fixing
https://github.com/hashicorp/terraform/pull/8607 . Specifically when
resources in the statefile are deleted or missing in real life, then
terraform plan would exit with an error when it recieved a 404 not
found. The correct behaviour would be to show a plan with the offer to
create the missing resources.
When setting the certificate_url and certificate_store values in
os_profile_secrets / vault_certificates for a Windows VM in AzureRM, I
was getting the following error:
```
[DEBUG] Error setting Virtual Machine Storage OS Profile Secrets:
&errors.errorString{s:"Invalid address to set:
[]string{\"os_profile_secrets\", \"0\", \"vault_certificates\"}"}
```
This seems to resolve the issue.
