NO-ISSUE: retry image pull in all cases

[tsorya]

NO-ISSUE: in some registries (brew for example) we can get a redirect to another registry that doesn't have this specific image manifest and we will get manifest-unknown error and will not retry to pull it, removing this pretty small optimisation will allow us to retry in this case and make our code more error resilient

Why would retrying suddenly fix this? - Is the registry redirect temporary?
