Fall out from: https://issues.redhat.com/browse/COST-2875

Currently when you order_by[distributed_cost] with filter[limit] all items in the response are ordered in the return including others. 

So depending on the cost, we can have order like:

project1 - 13 Others - project2 - project3.

We need to move `13 others` to the end of the list so, that the top elements are our "costliest" projects. There is currently a work around in place for the UI so this SHOULD NOT block the epic from being marked done. However, we would like the others to be moved to the end of the return to be consistent with how our other endpoints work and make QE testing easier. 

Problem is most likely associated with how our ranked_list logic works.
