Job is not retried after failure caused by grpc error

[mrhackcz]

Describe the bug A job with retries > 0 that failed by this error is not retried.

grpc: Error on execution streaming, agent connection was abruptly terminated: rpc error: code = Internal desc = grpc: error while marshaling: marshaling types.AgentRunStream: size mismatch (see https://github.com/golang/protobuf/issues/1609): calculated=219, measured=128

To Reproduce Steps to reproduce the behavior:

1. Create a job with retries > 0
2. Wait, because I don't know why it's happening and how to reproduce it

Expected behavior The job should be retried when it fails.
