In cases when kpet matches no tests (e.g. a combination of a specific test set and an unsupported tree), the test plan is not empty - there is NO test plan, i.e. there is no "tests" list entry in the kcidb file.
Handle this situation gracefully, without crashing the pipeline. Luckily
we're not on RHEL6 in the setup stage and can thus use the ?
syntax is
jq.
