Docker Executor: "Preparation failed: no such image" is no longer mysterious

What does this MR do? & Why was this MR needed?

Previously it wasn't clear what image is missing. That was caused by the fact the code didn't print service name and version before raising error. Now it's clear.

Are there points in the code the reviewer needs to double check?


Does this MR meet the acceptance criteria?

I guess these all are N/A due to simplicity of this contribution.
