Fix latest tag check (#426)

Our check that (when we make a new release) the Docker image is tagged
with latest as well as the new semver version number, which we added in
[v1.6.14][1] was broken. This was because we were not pulling the latest
tag docker image during the check, so it was not present. Fixed in this
commit.
