[I] Optimizer schema change assert error has incorrect error [arrow-datafusion]

["curtisleefulton (via GitHub)" <gi...@apache.org>]

curtisleefulton opened a new issue, #9010:
URL: https://github.com/apache/arrow-datafusion/issues/9010

   ### Describe the bug
   
   In datafusion/optimizer/src/optimizer.rs:271 when calling `assert_schema_is_the_same` prev_plan / new_plan are backwards. This causes an incorrect / confusing assert error, indicating the optimized plan is actually the original plan.
   
   ### To Reproduce
   
   Any optimization error that produces a schema change will reproduce this bug.
   
   In this particular case, the root cause of the schema change dropping timezone metadata for timestamps somewhere in  the Optimizer rule `simplify_expressions`. Fixing this bug will help find the root cause.
   
   ### Expected behavior
   
   _No response_
   
   ### Additional context
   
   _No response_
