Set-DbaNetworkCertificate - Take the thumbprint raw from the remote scriptblock in the test

Invoke-Command2 wraps plain output in a PSCustomObject unless -Raw is used, so the CNG test
handed the command an object with a Length property instead of the thumbprint and failed on
the thumbprint format check.

(do *NetworkCertificate*)
