rCOMM61665dd80d82: [services] Backup/Blob - Make sure Finish is only called once
Summary

Depends on D3636

We should make 100% sure that Finish (the method provided by gRPC) is called no more than once. Otherwise, it's going to crash.

Test Plan
cd services
yarn run-blob-service
yarn run-backup-service
