fix: regression in resolving the right versions

Motivation and Context

commit d480022 caused a regression in real
resolver, by picking up incorrect versionID.

How to test this PR?

Tests already cover this case, however, we need to
fix mc so that it can fail when server returns '503'

For that we need a fix minio/mc#4172 this
is why this regression was missed.
