select min/max(string dictionary) panics

[NGA-TRAN]

Describe the bug
SELECT min/max(dictionary_string_column) will panic with the following message:
ArrowError(InvalidArgumentError("column types must match schema types, expected Dictionary(Int32, Utf8) but found Utf8 at column index 0"))'

To Reproduce
Add the below test inside query_on_string_dictionary, you will hit that bug.

    // aggregation min
    let sql = "SELECT MIN(d1) FROM test";
    let actual = execute(&mut ctx, sql).await;
    let expected = vec![vec!["one"]];
    assert_eq!(expected, actual);

Expected behavior
Query runs and returns correct results
