Emulator returns success for missing items when using batch endpoint

Probably similar to #7

When calling batch endpoint in real GCS, files that doesn't exist return NotFound. When using the emulator it never returns an error.

Real GCS returns an *googleapi.Error with Code 404

That's a lot of negativity could we rephrase in a positive way? 🤣

"Emulator returns success for missing items when using batch endpoint" or something
