[GraphHopper] Graph construction

Hi Thomas,

graph from the first test is reused/loaded

Hmmh, that is strange as you would need to explicitely load the graph
and you have to enable 'store':
GraphStorage graph = new GraphBuilder().store(true).create();
Or if you would use mmap I could explain the behaviour.

Would you mind to post the unit tests? The best would be to reduce them
to the minimal code required to reproduce your issue.

> And is it possible to reassign an edge? So I can insert new nodes
between existing ones.

you cannot delete edges at the moment. But adding new one or overwriting
properties is possible.

Regards,
Peter.
