Version 1 of just-clone casts everything to an object, even though in this case it was a string (I am not sure if this was wanted behavior, but it resulted in a failed test).

The newer versions don't do that, just like klona.

This is here to preserve that behavior.

if (_moduleParams.keyName) {
script.prebidData.kn = _moduleParams.keyName;
}

Version 1 of just-clone gives back an empty object when the cloning fails.

The newer versions don't do that, just like klona.

This is here to preserve that behavior.
