Fix delete versioning objects when previous is expired

When deleteing versioned objects proxy will try to restore the previous
copy. The COPY request will fail if the previous version is expired but
not handled by object-expirer.

This patch checks COPY respones on the previous copy, if it's
HTTP_NOT_FOUND(mostly because it's expired) proxy will try to restore
with the version before previous.
