TestResourceStatusClient.replaceStatus doesn't write status if it doesn't already exist.

[gavares]

TestResourceStatusClient.replaceStatus does not insert a .status section if one does not already exist because of the call to .mapStatus.

The word "replace" in the name of the function might mean that this behavior is intentional but there doesn't appear to be a createOrUpdateStatus function and replacing the entire CR doesn't seem like the right thing to do when an operator should really only be modifying .status and perhaps .metadata.
