aggr=[[COUNT(UInt8(1))]]

### To Reproduce
```
#[tokio::test]
async fn test_count_wildcard_on_where_scalar_subquery() -> Result<()> {
// you can find create_join_context() in
datafusion/core/tests/dataframe.rs
let ctx = create_join_context()?;
ctx.sql("select a,b from t1 where (select count(*) from t2 where t1.a =
t2.a)>0;")
.await?
.explain(false, false)?
.show()
.await?;
Ok(())
}
```
