Project name shouldn't be inside the project

[nsheff]

Right now, the project 'name' (which is used in the registry path) is stored inside the project itself in the config file.

This leads to confusion, like when I try to paste a local PEP in and it lacks the 'name' field. It's not immediately obvious that 'name' mean the name of the repo.

Analogy to a git repo: it's as if the name of the repo was somehow stored inside the repository. This is unnatural. In the future we should change this.
