    Stop logging versions on every agent update

    This logging statement was being called on every agent update
    even if no versions changed, resulting in a bunch of useless
    messages.

    We already log when the actual versions change in the _set_version
    call here: [1]

    To cover the cases where versions are removed, this adds two logging
    statements so we can be sure we see when the tracked versions do
    change but not be bothered by version logs in any other condition.

    1.
