Migration Plugin

After a migration with errata, if i query the migrated content api:

# curl  --cert /etc/pki/katello/certs/pulp-client.crt  --key /etc/pki/katello/private/pulp-client.key https://`hostname`//pulp/api/v3/pulp2content/6a06b9d9-0cc5-4c28-aea5-ad4ff9f76a48/

I get:

{
  "pulp_href": "/pulp/api/v3/pulp2content/6a06b9d9-0cc5-4c28-aea5-ad4ff9f76a48/",
  "pulp_created": "2020-06-11T14:41:18.350552Z",
  "pulp2_id": "7c084d6e-073e-4310-94e3-5ab06b66ef1e",
  "pulp2_content_type_id": "erratum",
  "pulp2_last_updated": 1591886473,
  "pulp2_storage_path": null,
  "downloaded": false,
  "pulp3_content": "/pulp/api/v3/content/rpm/advisories/19182792-dc5f-4200-84ca-78a7791d8ad4/",
  "pulp3_repository_version": "Noneversions/1/"
}

notice that the pulp3_repository_version is not a valid version.

This only happens after re-migration (and it almost appears that it happens on the 3rd migration of the same plan). In this caes the repos are deleted between each run:

1. create repos in pulp2 and run a migration plan similar to this:

{"plugins"=>[{"type"=>"rpm", "repositories"=>[{"name"=>"pulp-uuid-rhel_6_x86_64", "repository_versions"=>[{"pulp2_repository_id"=>"pulp-uuid-rhel_6_x86_64", "pulp2_distributor_repository_ids"=>["pulp-uuid-rhel_6_x86_64"]}], "pulp2_importer_repository_id"=>"pulp-uuid-rhel_6_x86_64"}, {"name"=>"Published LIbrary view-355376805-405955044", "repository_versions"=>[{"pulp2_repository_id"=>"8_view1_archive", "pulp2_distributor_repository_ids"=>["8_composite_version1", "8_composite_version1_archive", "8_view1", "8_view1_archive"]}]}]}]}

2. delete the pulp2 repos and re-run the migration plan
3. maybe repeat step 2?
