…asonable ### What changes were proposed in this pull request? Some testing CASE WHEN queries are not carefully written and do not make sense. In the future, the optimizer may get smarter and get rid of the CASE WHEN completely, and then we loose test coverage. This PR updates some CASE WHEN queries to make them more reasonable. ### Why are the changes needed? future-proof test coverage. ### Does this PR introduce _any_ user-facing change? 'No'. ### How was this patch tested? N/A Closes #36125 from beliefer/SPARK-37960_followup3.
