tableWithUTFCharacters throws IndexOutOfBoundsException when INSERT/CREATE statement is executed

ref. https://github.com/apache/zeppelin/commit/0fc1d7ba2081ebeed5c45d87c27ca57727f54099

• The error occurs in parseSQLJsonOutput (line 180) as it always expects rowsOutput to have at least 2 values.
• When INSERT/CREATE statement is executed, the rowsOutput is empty, the app throws IndexOutOfBoundsException
