Check if the bucket exists before deleting VSP

Checks if the bucket exists before deleting VSP, ignoring the deletion
if the bucket isn't present anymore.
This avoids problems in case the artifact was already deleted from the
artifact storage, but for some reason the VSP still present in the
system.
