Astar turn restriction eager blocking fix

[tkalvas]

This is pretty terrible to look at, but it accomplices a couple of goals:

• It does not touch the core AStar/ShortestPathTree code at all
• The terrible possible looping when isCloseToStartOrEnd returns true is completely removed, leading to improvement in car routing speed
• Now we find the car route we are looking for

Fixes #6531.
