missing foes from internal junction incLanes

[namdre]

• the condition (forbids || rightTurnConflict) && (needsCont || dir=turn) is to restrictive
• the condition (forbids || rightTurnConflict) && (needsCont || dir=turn || !ts) works correctly for non-tls junctions
• the condition (forbids || rightTurnConflict) adds foes from the underlying priority junction and this is invalid as it could cause vehicles from the minor direction to become stuck on the intersection once their green phase runs out
• an extra check should be done to distinguish between direct and indirect bicycle turns: if the internal lanes from the same edge intersection after the internal junction, then the bicycle mu st yield. Otherwise it performs a direct left turn and traffic from the same edge must yield (Provide means to model indirect left turns #4252)
