routing: revert the swapping of in/out edges during path finding

Browse Source 
In this commit we revert a commit which was added in the past as way to
allow the path -> route conversion code to remain the same, while
properly respecting the necessary time locks and fees. In an upcoming
change, this swap is no longer necessary as we’ll always use: the time
lock of the outgoing node and the fee of the incoming node.
