heptapod-ci: remove push exception for named branches

The internal workings of Heptapod cause even fast-forward merges to look like
pushes to Gitlab. The only way to run a pipeline on topic-less named branches
is not through the web interface. I am probably the only person affected by
this, so it's not really a problem.

This was confirmed with Georges, the maintainer of Heptapod, though the only
way to be *actually* sure, is to merge this and see.
