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.

 # Don't run pipelines on branch "merge", since we're fast-forward only.
 # Gitlab sees a new branch (since e.g. `topic/stable/my-topic` becomes
 # `branch/stable`), but the hash hasn't changed. There is no reason to
 # re-run the CI in our case, since we haven't built up any specific automation.
 # Right now it's just wasted CI and developer time.
