Walking navigation doesn't find the shortest path

[liat-eytan]

When requesting navigation between 2 points (walking navigation) on some scenarios the returned paths are not the shortest path.
As an example, when I request the shortest path between point=41.38238279999999,2.0392181 and point=41.38402019999999,2.0448637 this is the result I get:

I would expect to get:

This seems to be a data issue. If you put a via point there you can see that it will take a big detour at the destination:

It is also related to graphhopper/graphhopper#82 and graphhopper/graphhopper#2805 and maybe also graphhopper/graphhopper#2807
