Add group member mapping to existing
Add group member mapping to existing

Group members were being added with the member's imported name even if there is a mapped existing object name.
Added a check if object name is in the mergedObjectsMap and replace userGroupMember with the name in mergedObjectsMap.
Leaving print(userGroupMember) on the line before for logging visibility of the mapping name change in the console output.
