Chutney test-network and test-network-all fail on master branch
`make test-network` and `make test-network-all` are failing in my system with a clean version of master branch. It is failing since I pulled the commit [8b0b850efa0](https://gitweb.torproject.org/tor.git/commit/?id=8b0b850efa0f77b627f31e9907acc6d29482f362), here is the log of basic-min test.
```
Using Python 2.7.14
test003c is running with PID 21530
1/4 nodes are running
FAIL basic-min (exit status: 3)
```
I am getting this error with all network tests. If you need more information let me know.
