Race-track orbit 2nd point landing bug

[toutenglisse]

Found by mistake, it's idiot..., but if AI has 2 wpts : 1 with race-track orbit and 1 landing point, it dives and crashes vertically at start (RTOrbit-2ndPoint-landing-1.trk).

If it gets another wpt before the 1 with race-track orbit, it doesn't crash but the 2nd orbit point is not placed on the landing wpt (it is "projected" so the race-track is oriented 90°/270° - RTOrbit-2ndPoint-landing-2.trk).

If 2nd race-track orbit point is not a landing point then all works normally.
