drivers/docker: fix flaky image coordinator test 

The test assertion that we don't have a delete future remaining races with the
code its testing, because the removal of the image and the removal of the
future are not atomic. Move this assertion into a `WaitForResult` to avoid
test flakes which we're seeing on CI on Windows in particular.
