Remove repeat errors

[bia]

Describe the bug

From my slack conversation with @luizbafilho, there is an issue with how k8s reports certain errors. it errors out on two versions of the same crd, ideally they would report something like trafficsplits.split.smi-spec.io/v1beta1 and trafficsplits.split.smi-spec.io/v1beta2 but they ignore the crd version.

In order to avoid this case (and similar ones) we should string-match the error output and only display one if they are identical.
