[Fix](Planner) fix arguments type changed to array type and implicitly cast child error

[LiBinfeng-01]

Proposed changes

Problem:
When querying sql with expression like count(case when...) Planner would return an implicitly cast error
Example:
select count(case true when true then null else null end) from t;
Reason:
When analyzing count function, it would expect return type of case when is a scalartype, if not, it would cast them into scalartype implicitly.
Solusion:
Open the switch of casting null to array, because this analyze happened before folding expression to constant
