Plugin manager downloads returning 404 treated as zip

[emesare]

On latest dev you cannot download certain plugins as they are returning 404:

This is returning 404 but on the client it manifests as a failure to unzip, that is because the body was placed on disk as a zip instead of the status code failing early, which it should do instead.

The more pressing issue of the downloads no longer being available has been resolved, now its only the issues regarding the client code not checking the returned status before continuing, demoting to impact low.
