reproduce:
netgenerate --grid --grid.number 1 --grid.attach-length 100 -o net.net.xml --lefthand --no-turnarounds -j traffic_light

link 0 and 8 both yield for each other creating a deadlock

the function NBNode::tlsContConflict is called when writing the response string and thus has to consider lefthand-setting which it currently does not do.
The solution to pass a lefthand argument is somewhat ugly since lots of methods are called that also give lefthand-sensitive results. A better solution might be to compute and store the junction logic before mirroring.
