This is bad. Can you please add one testcase in TestBuiltin including both two UDFs for the case of accumulator?

> When using MIN/MAX UDFs with strings in a job that uses the accumulator interface the results are wrong - The UDF won't return the correct MIN/MAX value.
> this is caused by a reverse 'GreaterThan/SmallerThan" (<>) sign in the accumulate() function of both StringMin/StringMax UDFs.
