CI: 'SpecifierSet' object has no attribute 'split'

[shortmann]

Currently the Travis build job is not working.
It looks like the same problem
ansible/molecule#2350

Yep, pain isn't it? ;)

You'll find some answers over @ ansible/molecule#2350

Well, I fixed it like bristea @ ansible/molecule#2381
But the unit tests are not working. I need more time to understand how the new plugin/driver system should work. ;-)

[decentral1se]

Noice. I got the unit tests working for my latest work on the Hetzner Cloud plugin over @ https://github.com/pycontribs/molecule-hetznercloud. It's very minimal for now but will do while we keep working on porting things out. Maybe that can help for now.

Fixed in master.
