Unexpected RoadLanes created when RoadPoints are moved

[bdog2112]

Observed an issue where unexpected RoadLanes were created. This led to other unexpected behavior.

How to recreate problem:

• Open Main or Dev branch
• Switch to code editor, append sample code to end of RoadSegment.generate_lane_segments (see below)
• Save and restart
• Create a new scene with a RoadContainer as root
• Add a 2x2 Road from the menu in the 3D view
• Select RP_001 and RP_002 in the Scene dock
• Drag transform widgets to move the RoadPoints in the 3D view
• Upon release, observe message in Output panel saying, "RP_001 has 8 RoadLanes" or something to that effect.

A 2x2 road should have only 4 RoadLanes.

[Sample Code] var count = 0 for ch in _par.get_children(): if ch is RoadLane: count += 1 print("%s %s has %s RoadLanes" % [Time.get_ticks_msec(), _par.name, count]) return any_generated
