some work has been going on with unnest, and somehow this bug can no longer
be reproduced
```
async fn test_unnest_used_to_be_broken() {
let ctx = SessionContext::new();
// this works:
// let v = lit("x");
let v = lit(ScalarValue::Dictionary(
Box::new(DataType::Int32),
Box::new(ScalarValue::new_utf8("x")),
));
let make_array_udf_expr = Expr::ScalarFunction(ScalarFunction::new_udf(
make_array_udf(),
vec![col("column1")],
));
let plan = LogicalPlanBuilder::values(vec![vec![v.clone()]])
.unwrap()
.project([make_array_udf_expr.alias("array")])
.unwrap()
.unnest_column("array")
.unwrap()
.build()
.unwrap();
let df = ctx.execute_logical_plan(plan).await.unwrap();
}
```
This works without any error
