Summary:
The **motivation** for this PR is my sad colleague bestander: I managed to break travis with bd60d828c5, without considering the consequences. This PR solves this failure, and will fix it for good.
**Test plan (required)**
Travis will demonstrate that the code is solid.
Let’s make sure tests pass on both Travis and Circle CI.
