meta=none will cause post-hooks to run in working directory

[brenmous]

Describe the bug
When using openapi-python-client generate --meta=none, post-hooks are run in the current directory.
This is an issue if you run the command in e.g. your home directory, as hooks will then run recursively and operate on everything they can find.

The culprits appear to be here:

openapi-python-client/openapi_python_client/__init__.py

Line 87 in 47e576c

self.project_dir /= self.project_name

here:

openapi-python-client/openapi_python_client/__init__.py

Line 157 in 47e576c

cmd, cwd=self.project_dir, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE, check=True

and here:

openapi-python-client/openapi_python_client/config.py

Line 31 in 47e576c

"autoflake -i -r --remove-all-unused-imports --remove-unused-variables --ignore-init-module-imports .",

To Reproduce
Steps to reproduce the behavior:

1. Make a new directory
2. Add a subdirectory, inside include some random python file with e.g. an unused import
3. Go back to the parent directory
4. Run openapi-python-client generate --meta=none [--path=...|--url=...]
5. Your python file in the subdirectory will have been formatted, e.g. unused import removed

Expected behavior
I'd expect post-hooks to only ever be run in the directory generated for the client.
