Temporary changes to sprucing tests from !2734 need to be reverted after `Spruce_EoY23`

!2734 (merged) introduced the Sprucing ZTrkEff lines for Spruce_EoY23 and this required several small changes to the existing sprucing tests. Once we remove these lines for Spruce_24 in !2683 (merged) these sprucing test changes should be removed.
