The AfterAll() and AfterEach() blocks in the test file for custom calls
run everytime, even if the Context block for the actual tests is
skipped. In that case, running the final blocks results in an attempt to
remove deployments that have never been set up in the first place. This
may lead to the blocks failing when the tests were in fact skipped, and
may produce test artifacts even though Jenkins does not considered the
test failed.
Let's reorganise those blocks, to make sure they are called only when
necessary. Note that we do need to keep both DeleteCilium() and
DeleteAll(), even if they are now in the same block, as calling only
DeleteAll() would not remove the Cilium ConfigMap.
