recurring 403 errors while provisioning the conflict-practices repositories

**Problem:**
The generation of the conflict-practices repositories cannot be handled unattended. It requires a lot of reruns on bigger classes and takes full concentration that you cannot give your class while resolving this. The bigger the class the bigger the problem

**Observed behavior:**
The generation of the conflict-practices repositories (option 4 in the scrip) is giving recurring 403 errors. Every 4th repository it is trying to make results into HTTP 403 Forbidden warning. Every consecutive repos gets the same.

**Workaround:**
This requires you to rerun the script, skipping every repository you already created. You will need to do this roughly for the #contributors / 4.

**Expected behavior:**
Script generates conflict-practices repositories unattended while I can focus on teaching the class
