Resolves #72

It would be great if you could leave a short notice (that you are going to take over) in the future before opening a new PR - As in giving me a chance to fix the PR. That way we don't run into this situation where two people work on the same stuff (wasting work time).

@fubhy I'm sorry your effort was wasted.

I did reference your PR from mine, though it doesn't spawn a notification. I could've been more explicit. @Snugug probably should've briefly explained the reason when closing your PR.

But when you saw your PR was closed, why didn't you look into why?

[fubhy]

Because I already started working on the next PR when @Snugug commented on it the first time ;)

[Snugug]

@fubhy this is my bad and I'm sorry. Given the time of day I thought you would be unavailable.

No worries. Many things came together here (including me not actually checking back with GH before continuing to work on it and no e-mail notifications for referenced PRs, etc.). After all it was just a simple PR with literally only like 10 lines of search&replace fixes for the tests. So really not tragic.
