This test case would only work on e2e tests

we don't need to test ShouldCheckStandbyLag regression but it'd be great to add a simple unit test that covers PerconaPGCluster.Version() behavior

No, this only falls back with the assumption that the opeator will reconcile the cluster and set the version asynchronously. Falling back to version.Version() on non empty can introduce hard to find bugs. But a way to do it, would actually be a validation pattern on the CRD
