The bug in LivySparkSQLInterpreter is caused by this PR.
LivySparkSQLInterpreter delegate LivySparkInterpreter to generate
InterpreterResult and then convert it to table type. So here since we make it
as multiple InterpreterResult, we should only convert the InterpreterMessage
with text type that is for sql output.
