#### Overview of the Issue

Build of an AMI with HCP Packer Registry integration and with skip_create_ami = true ends up in creating an incomplete Iteration in HCP Packer Registry.

#### Reproduction Steps

1/ Export the HCP_CLIENT_SECRET and the HCP_CLIENT_ID locally as per : https://developer.hashicorp.com/packer/tutorials/hcp-get-started/hcp-push-image-metadata#create-hcp-service-principal-and-set-to-environment-variable
2/ Run the following:

```hcl
packer {
required_plugins {
amazon = {
version = ">= 1.0.1"
source = "github.com/hashicorp/amazon"
}
}
}

source "amazon-ebs" "basic-example-east" {
region = "us-east-2"
source_ami_filter {
filters = {
virtualization-type = "hvm"
name = "ubuntu/images/*ubuntu-xenial-16.04-amd64-server-*"
root-device-type = "ebs"
}
owners = ["099720109477"]
most_recent = true
}
skip_create_ami = true
instance_type = "t2.small"
ssh_username = "ubuntu"
ssh_agent_auth = false
ami_name = "packer_AWS_{{timestamp}}"
}

build {
name = "example-amazon-ebs"
sources = [ "source.amazon-ebs.basic-example-east"]
hcp_packer_registry {
bucket_name = "example-amazon-ebs-custom"
description = "Golden image for Amazon-backed applications"

bucket_labels = {
"team" = "amazon-development",
"os" = "Ubuntu"
}

build_labels = {
"python-version" = "3.9",
"ubuntu-version" = "Xenial 16.04"
"build-time" = timestamp()
}
}
}
```

Error: failed to complete HCP-enabled build "example-amazon-ebs.amazon-ebs.basic-example-east"

failed to update Packer registry with image artifacts for
"amazon-ebs.basic-example-east": setting a build to DONE with no published
images is not currently supported.

Build 'example-amazon-ebs.amazon-ebs.basic-example-east' finished after 1 minute 46 seconds.

==> Wait completed after 1 minute 46 seconds

==> Builds finished but no artifacts were created.

Iteration "XXXXX" is not complete, the following builds are not done:

* "amazon-ebs.basic-example-east": RUNNING

You may resume work on this iteration in further Packer builds by defining the following variable in your environment:
HCP_PACKER_BUILD_FINGERPRINT="XXXXX"
```

Ideally, HCP Packer Registry push should be ignored by Packer since this is a test build and no AMI will be created upon the packer process.

Hope this makes sense.

Thanks a lot for your help.

Bests.
