Add missing await statement in docker.Image Python implementation.

[jkodroff]

Fixes #366

Note that I eyeballed this code. I was not able to consistently reproduce, but based on reading the code and my intermediate understanding of Python, every async function should be called with await.

Hello @guineveresaenger @jkodroff Was wondering if there are any updates on this?

Hi everyone!

Unfortunately, it appears as though this does not persistently fix the underlying issue.

We do have efforts underway to address this and other issues more robustly, so I will be closing this issue for now.
