nzS3Connector: While downloading backup files from cloud, it says download completed even if backup of database doesn't exist.

[nmn1406]

Tried to download backup files by giving random/wrong DB name (Db doesn't exists, backup was never taken) and backupset id.

It says download complete. Nothing is downloaded.

Expectation is that it should throw error, like file doesn't exist on cloud.
