Fix more tests for removal of waypoint nodes.
Merge branch 'master' of https://github.com/engaric/graphhopper
Repair test file, fix test case for tower->pillar

coordinates at start and end of polyline should match start and end
node coordinates.
waypoint nodes which are not part of route information become geometry
nodes (pillars) not tower nodes.  Fix test for that change,
Fix another test for geometry nodes
Fix another test for removal of waypoint nodes
Turn restriction test fix

At the moment orientation of directed links is not used for turn
restrictions so restriction direction is list order based.  So
mandatory turn was from 17 to 19 not 19 to 17. Correct test file to
have start and end points of polyline match start and end nodes.
