KUTTL: don't bail out immediately, save the test reports

Execute all KUTTL tests without bailing out at the first error.
Instead make sure that the tests are executed and their JUnitXML
reports are collected if available.
Move the accept/fail condition at the end, following the same
pattern used elsewhere when running tests.
