Seed List Doesn't Show All Seed Images If Using Filter=reference

[emimaesmith]

The seed list command is meant to display a list of all seed compliant docker images located in the current environment. However, it neglects to include any seed compliant images that have been pulled down from a registry if it detects the version of docker on the system supports the --filter=reference option from docker images.

For example, performing a seed pull -in my-job-1.0.0-seed:1.0.0 -r my-registry -o my-org, then docker images results in the following image displayed in the list:

REPOSITORY                                           VERSION
my-registry/my-org/my-job-1.0.0-seed                 1.0.0

However, performing a seed list will not return this image if the version of docker supports the filter reference.
