unresolved dependency pytest-runner on python 37 install

[Warpulis]

I'm on a new python 3.7.4 on Windows 10 and tried to

C:\Python37\python.exe -m pip install --proxy "<removed>" pynvim

The process hangs and after Ctrl-C I got an error message about the missing dependency

distutils.errors.DistutilsError: Could not find suitable distribution for Requirement.parse('pytest-runner')

After

C:\Python37\python.exe -m pip install --proxy "<removed>" pytest-runner

pynvim installs just fine.

P.S.: Full log output:

should be fixed by #418 but I'm thinking we should remove it entirely.
