Bugtest SUMO Crashing on Turns

[Gamenot]

This one seems to occur in just the second episode of loop. Replicate with just a call to supervisord and Eclipse SUMO sumo Version 1.8.0.

@Adaickalavan I found out one of the reasons why we could not reproduce the sumo crash on docker.

For some reason Docker is installing a different version of smarts in the image. I am getting smarts==0.4.12 even when creating a smarts 0.4.13 image.

I have managed to reproduce the issue on Docker now but the SMARTS version on docker issue will need to be solved.

I have put up an image that should be able to reproduce the problem https://hub.docker.com/layers/huaweinoah/smarts/bugtest_0.4.13-sumo_1_8_0/images/sha256-51025124ec25309e923893c59c569939d788983fd76d7e5b3bac116d9c3dddcb?context=repo .

# `-v $PWD:/src` can be used
$ docker run --rm -it -p 8081:8081 huaweinoah/smarts:bugtest_0.4.13-sumo_1_8_0
$ scl envision start -s ./scenarios -p 8081 &
$ scl scenario build scenarios/loop --clean
$ python examples/single_agent.py scenarios/loop

I ran the given commands on the docker image.

Test outcomes are as follows. Each test was started afresh by restarting the docker and re-running all commands.

Test #	Outcome
1	Traci connection error in 3rd episode
2	Finished all 10 episodes without any errors
3	Finished all 10 episodes without any errors
4	Finished all 10 episodes without any errors

Perhaps, the docker image should be tested multiple number of times by more people @iman512003 @JingfeiPeng.

Going to try using #612 to get this to become fully reproducible.

#619 is looking at this issue more in depth.
