Review comment:
The intention was passing null parameters as they are so that
`SqlParameterizerShuttle` and `RelParameterizerShuttle` can handle them
properly. They will throw `InvalidArgumentException` at
https://github.com/apache/druid/pull/11900/files#diff-ae4b6e9293a80177b076ab1a7d6235931eb95619dcc759ae40027543ef35f4e1R215

Do you think it's better to throw an exception here too? I thought it would be
better to put error handling logic in one place.
