lodash so we can use _.transofrm

+    Derby stores the user schema a bit different than other apps prefer. The biggest difference is it stores
+    tasks as "refLists" - user[taskType + "Ids"] & user.tasks - where 3rd party apps prefer user[taskType + "s"] (array)
+    This function transforms the derby-stored data into 3rd-party consumable data
+    {userScope} the user racer-model scope, NOT an object
+    {withoutTasks} true if you don't want to return the user.tasks obj & id-lists. We keep them around when doing
+      local ops, because the var-by-reference lets us edit the original tasks
