[MRUNIT-213] MultipleOutputs for Reducers throws Named output 'test' not defined

Description

I pulled the unit test for testing multiple outputs for a reducer from the patch of MRUNIT-13 and the test fails with the exception:

java.lang.IllegalArgumentException: Named output 'test' not defined
at org.apache.hadoop.mapreduce.lib.output.MultipleOutputs.checkNamedOutputName(MultipleOutputs.java:188)
at org.apache.hadoop.mapreduce.lib.output.MultipleOutputs.write(MultipleOutputs.java:358)
at org.apache.hadoop.mapreduce.lib.output.MultipleOutputs.write(MultipleOutputs.java:343)

It looks like multiple reducer outputs needs to be setup in the Configuration object the same way MultipleOutputs.addNamedOutput() does.

I'm running cdh4.6.0
