path dependency inside a git dependency raises error

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Debian GNU/Linux 10 (buster)
• Poetry version: 1.1.12

Issue

I have a project (A) that has a git+ssh dependency (B). B itself has a pyproject.toml that includes a path dependency (C - a wheel inside the repository of B).
If I run poetry install in A it will happily install B but it gives an error for C. It seems the issue is that the path to the "path dependency" C does not exist during the dep solving process - before cloning B - and therefore all properties of PackageInfo are None, not initialized. It fails here with name and version being None : https://github.com/python-poetry/poetry/blob/5814e335221047bbd5ca4d7def6994acc0a9c1ca/src/poetry/inspection/info.py#L141-L143

If I change the dependency B inside the A project.toml to a local path (instead of git) C is also installed and all works fine. The issue is present for a "path" dependency inside a git dependency.

Some background: C is a wheel (rust bindings) in a private repo that I "wrapped" in a pyproject.toml (I can not use setup.py "install_requires" together with poetry).

Thank you

Reproduce the failure with project A depending on git project B, where B declares a path dependency on wheel C. Inspect src/poetry/inspection/info.py around lines 141-143 and trace the dependency-solving path before B is cloned. Done means Poetry installs C successfully through the git dependency without the reported None name/version error.
