Test the validity of the chain produced when device-unique attestation is requested. When the caller requests that the key attestation be signed using the device-unique attestation key, the chain will look different than a chain signed by the batch key (common case): (1) The chain is exactly of length 2. (2) The root is self-signed and is unique to the device. Test that the chain is correctly signed in this change. The root is not currently correctly self-signed, so don't test (2) yet.
