This causes strange things if the route does not contain the ;lr 
parameter. In this case, the Route header - which contains the final 
target - is removed and the RURI contains the route.

Maybe this could be solved by removing the Route header before doing 
loose-strict conversion, (or drop strict-router support and behave as 
the ;ls parameter is always present)
