Reverts r1592530 for OFBIZ-5629. Ahmad Ludin reported on dev ML that it was not working. I'm sure I saw it working,  now wonder how it did work.

I also spotted something weird. If you change the name of the performFind result-map-list from listIt to eg listIts (in both performFind and removeDuplicateWorkEfforts), you get no results
