routing: modify path finding tests to accommodate for flip in fee calc
Before this commit, we would expect that structurally we don’t pay any fee for the first hop, but do for the final hop. After the latest commit, this is now flipped as when we say fee, we mean the fee that we need to pay to transit a link. For the final hop, there’s no additional distance to be traveled, so the fee is nothing.
