fix_s3_nonencrypted_to_encrypted_xva

Hello Florent,

Branch built and testing
Test procedure: removed the minPartSize=100000000 from remote definition, deleted the b2 backup and restarted the mirror backup. There are some other VMs that will also be uploaded to B2 so it will take a while. Expect feedback tomorrow.

Thank you,
Pedro
