   ### What problem does this PR solve?
   
   Issue Number: None
   
   Related PR: None
   
   Problem Summary: Eager aggregation could reach a logical relation with no 
aggregate functions or group keys and generate an invalid empty aggregate. 
Return the relation unchanged for this empty push-down context and add a 
focused unit test covering the visitor path.
   
   ### Release note
   
   Prevent eager aggregation rewrite from generating an empty aggregate on a 
relation.
