Unable to find the correct QA image for preprod

We us preprod for validating official releases, which have official tags. I believe the recent logic changes in gitlab-qa has made it so we can no longer pull a qa image for an official tag.

For example, on preprod we have:

Screen_Shot_2019-12-12_at_1.51.26_PM

Support::DevEEQAImage.new.retrieve_image_from_container_registry!('2a57951c0ee')

is failing because there are no tags that end with 2a57951c0ee, what we probably want is:

Support::DevEEQAImage.new.retrieve_image_from_container_registry!('12.5.4-ee')
