Sometimes, the `es-index-cleaner` fails because the `tests/cmd-utils/wait-cronjob/main.go` CLI fails reporting the following error:

    logger.go:42: 11:56:16 | es-index-cleaner/11-wait-es-index-cleaner | time="2022-01-27T11:56:16Z" level=error msg="The test-es-index-cleaner-with-prefix-es-index-cleaner CronJob was not found"

Steps to reproduce the behavior:
It is not easy to reproduce. You need to run a the test a lot of times until it happens.

This is making the CI fails randomly when the Jaeger Operator is working fine.
