All 4.5 to 4.6 skew tests have been broken for quite a while https://prow.ci.openshift.org/view/gcs/origin-ci-test/logs/release-openshift-origin-installer-old-rhcos-e2e-aws-4.6/1338185336429219840 due to a panic happening in code init, vs inside a test.  The panic completely blocks the test suite from running, vs just skipping one test.

Has to happen inside a test block.

This is not a backport (the bug only exists in 4.5 and can only be fixed in 4.5 z).
