grouper-duo, edu.internet2.middleware.grouperDuo.GrouperDuoFullRefresh.java needs to extend OtherJobBase

I'm getting this error message when running OTHER_JOB_duo.

java.lang.RuntimeException: The OtherJob should extend edu.internet2.middleware.grouper.app.loader.OtherJobBase, but it is: edu.internet2.middleware.grouperDuo.GrouperDuoFullRefresh

I think a patch broke this class.  Should just be a matter of causing GrouperDuoFullRefresh to extend OtherJobBase. 

Our grouper-loader.properties file contained the following properties..

otherJob.duo.class = edu.internet2.middleware.grouperDuo.GrouperDuoFullRefresh
otherJob.duo.quartzCron = 0 0 5 * * ?
