Looks like plus_one is whacked.

Going totally out on a limb. The other odd thing is we now get warnings on pyrsistent python library install. Maybe bump version back to 0.15.3? Note 0.15.4 released Jul 27. I have no idea if/how that might affect these tests. Will try it out and we can back it out if it doesn't help.

Hmm now no Travis run on the PR 🤦‍♂

Probably needs another look if this is needed.
