Problem

When switching between different manifests, a newly downloaded version might chronologically be older than all previously downloaded versions, even though it's marked as the latest version in its own manifest. This is why we are getting the EPIPE error when trying out the alpha manifest. The cleanup deletes the language server right after it was downloaded

Solution

In such cases, we skip the cleanup process to preserve this version. Otherwise we will get an EPIPE error. At this point the version that was downloaded shouldn't be delisted, so we don't want to make sure its not removed
