aider: Added a test method to check if get_commit_message returns the expected message when send method is mocked.

# Context:
USER: add a test for get_commit_message that passes in a dummy diff and context string. mock coder.send to return "a good commit message",False. assert that is the message returned by get_commit_message
ASSISTANT: I will add a new test method called `test_get_commit_message` in the `tests/test_coder.py` file.

```python
tests/test_coder.py
<<<<<<< ORIGINAL

if __name__ == "__main__":
    unittest.main()
=======
    def test_get_commit_message(self):
        # Mock the IO object
        mock_io = MagicMock()

        # Initialize the Coder object with the mocked IO and mocked repo
        coder = Coder(io=mock_io, openai_api_key="fake_key")

        # Mock the send method to return a tuple with a message and False
        coder.send = MagicMock(return_value=("a good commit message", False))

        # Call the get_commit_message method with dummy diff and context
        result = coder.get_commit_message("dummy diff", "dummy context")

        # Assert that the returned message is the expected one
        self.assertEqual(result, "a good commit message")

if __name__ == "__main__":
    unittest.main()
>>>>>>> UPDATED
```

This new test method mocks the `send` method of the `Coder` object to return a predefined commit message and checks if the `get_commit_message` method returns the expected message.
