KYLIN-5359 'replace' function expression convert error

[liuzhao-lz]

Proposed changes

statement "select name, replace(name, substring(name, 1, 1), '--') as new_name from LZ_TEST_YUFA " query failed,
errorMsg：java.lang.ClassCastException: org.apache.spark.sql.Column cannot be cast to java.lang.String while executing SQL: "select * from (select name, replace(name, substring(name, 1, 1), '--') as new_name from LZ_TEST_YUFA) limit 50000

Reason: In the ExpressionConverter, the substring returns a column object, while in the replace conversion, the function parameter is forced to be converted to a string.
