aider: Added a test for cmd_git that creates a temporary git repository, adds a file, runs the cmd_git method with the arguments "commit -a -m msg", and confirms that the file is in the repository.

# Aider chat conversation:

USER: write a test for `cmd_git`. use `GitTemporaryDirectory` to make a temp git repo. add a file. then run `/git commit -a -m msg` and confirm that the file is in the repo

ASSISTANT: To write a test for `cmd_git`, we need to modify the `tests/test_commands.py` file.

Here are the steps we need to follow:

1. Import `GitTemporaryDirectory` from `tests.utils`.
2. Create a new test method `test_cmd_git`.
3. Inside this method, create a temporary git repository using `GitTemporaryDirectory`.
4. Add a file to the repository.
5. Run the `cmd_git` method with the arguments `"commit -a -m msg"`.
6. Check if the file has been committed to the repository.

Here is the *edit block* for these changes:
