Skip a build if there are no jobs

[perlpunk]

My theory: due to a race condition there might not be any job left in a build,
when we start to process it, because all were jobs deleted meanwhile.

Issue: https://progress.opensuse.org/issues/192496

I think I can only unit-test this by splitting up compute_build_results.
I will have a look into it.

I was about to approve but I notice a tiny drop in the coverage. https://app.codecov.io/gh/os-autoinst/openQA/pull/6840/indirect-changes
it makes me think that it might not that simple as it looks like, Why does it effect this part in the cancel(). Could you take a look. Maybe is nothing

I assume that's a flaky coverage and is unrelated. My change has nothing to do with cancelling.
I can do a force push and see if it changes something.
