heptapod-ci: (hopefully) fix the pipeline savings system

There is no easy way for me to test this outside of the actual repo since
it would require setting up `heptapod-runner` locally, making a Git repo
with the right changes, etc. It's not worth my time at this point.

If this fails, I'll try to ask for help from Georges, the maintainer
of Heptapod.
