poetry: broken on master

[kierdavis]

Issue description

pythonPackages.poetry fails to build since it cannot find a package satisfying requests-toolbelt<0.9.0,>=0.8.0. The version of requests-toolbelt currently provided in nixpkgs is 0.9.1.

Cross referencing #55757 which contains the commit b86de1a which was probably the cause of this breakage.

Steps to reproduce

[kier@coloris:~/checkouts/nixpkgs]$ git pull NixOS master
From github.com:NixOS/nixpkgs
 * branch                    master     -> FETCH_HEAD
Already up to date.

[kier@coloris:~/checkouts/nixpkgs]$ nix-build -A python3Packages.poetry

Mine still says poetry is broken

[kierdavis]

@ryanpeach it was fixed in 19.03, but now it's apparently broken again in 19.09 (maybe for a different reason? I haven't had a chance to investigate).
