crate.version: Fix `latestUnyankedVersion` bug

`latestStableVersion` is already guaranteed to be `null` because of the previous condition. I assume the original intention here was to check for `latestUnyankedVersion` instead.

It looks like this bug was already present in the original implementation in #1857
