Splitted roads aren't always merged correctly and show straight line

[jfbourdon]

When a road is splitted in chunks because it is too long to be processed in only one, the corrected road sometime show a straight line between both ends of the line. The computed metrics doesn't seem to be affected by this line that can cross any terrain. I'm under the impression that fixing #62 will also fix this issue.

Je crois que ce problème est le même que l'autre. Les sous-parties sont inversées et c'est pour ça que ça semble se reconnecter
