aider: Refactor the test_main_with_empty_dir_new_file function in tests/test_main.py to correctly mock the get_commit_message function.

USER: I ran this command:

 pytest tests/test_main.py  -k test_main_with_empty_git_dir_new_file

ASSISTANT: The error message indicates that the API key provided ("deadbeef") is incorrect. You need to provide a valid OpenAI API key.

The API key is set in the `setUp
^C KeyboardInterrupt

USER: it's not supposed to be calling the real `get_commit_message`

ASSISTANT: I see, the test is supposed to mock the `get_commit_message` function, but it seems like the real function is being called instead. This could be due to the mock not being applied correctly.

In the `test_main_with_empty_git_dir_new_file` function in the `tests/test_main.py` file, the `get_commit_message` function is being patched. However, it seems like the patch is not being applied correctly.

Let's modify the test to ensure that the `get_commit_message` function is being mocked correctly.

Here is the change:

```python
tests/test_main.py
<<<<<<< ORIGINAL
    @patch("aider.repo.AiderRepo.get_commit_message", return_value="commit message!")
    def test_main_with_empty_dir_new_file(self, get_commit_message):
        main(["foo.txt", "--yes","--no-git"], input=DummyInput(), output=DummyOutput())
        self.assertTrue(os.path.exists("foo.txt"))
=======
    @patch("aider.repo.AiderRepo.get_commit_message", return_value="commit message!")
    def test_main_with_empty_dir_new_file(self, _):
        main(["foo.txt", "--yes","--no-git"], input=DummyInput(), output=DummyOutput())
        self.assertTrue(os.path.exists("foo.txt"))
>>>>>>> UPDATED
```

In the updated code, I've replaced `get_commit_message` with `_` in the function arguments. This is a common convention in Python when the variable is not going to be used. This change ensures that the mock object is not being confused with the actual function.
