Version 1.3.2
geopal: remove doublon of nodes

If an edge has the same point as begin and end two point was
created, and after that we have a doublon of id in the nodes
StreetNetwork: correction for oneway street projection

if the projection is near the target of an edge, we want to start from
the target but the reversal edge might not exists(for one way street for
example). we thus forbid to start from the source.
