[GraphHopper] GraphHopper init slowed down with 6c8f0549

[Peter K]

Ok, finally this should be fixed, although I will play a bit around to 
tune it.

Because I could apply a trick that I've tried some months before 
without effect. But now this trick gives us an amazing speed up of the 
preparation - it is only 50% of the original time :) ! E.g. world wide 
routing for bikes can be prepared in only 2h and full Germany is ready 
in 9 minutes (plus approx. 3min for import).

Regards,
Peter.
