IngressRoutes failing to sync update resources

[alehechka]

It was found through usage that when a synced traefik IngressRoute resource is updated, that the updater fails to do so. The error can be tracked all the way down to the traefik resource updater. It specifically complains about the resourceVersion not being allowed to be an empty string.

I have already tested the update sync on a default Service resource and that worked correctly.

This issue may be within the traefik package but that is unknown as of writing.

As this scenario isn't the most common and can be resolved by deleting the replicated resource and restarting the kube-external-sync deployment, I am not going to put a high priority on it at this time.
