On commit f0d34b7d9b
we changed the way we
did backports for OVOs during upgrades removing the need to have or
maintain `child_versions` fields in our OVO list classes.
This patch removes these fields that were introduced afterwards
including some that had the field incorrectly defined as
`child_version`.
