aider: Added test to check if get_tags_map function returns the expected tags map containing the file when ctags=False.

# Context:
USER: add another like that, but with ctags=False. just make sure the file is in the result.
ASSISTANT: I will add a new test to the `tests/test_repomap.py` file that checks if the file is in the result when `ctags=False`.

```python
tests/test_repomap.py
<<<<<<< ORIGINAL
            self.assertIn("my_function", result)

if __name__ == "__main__":
    unittest.main()
=======
            self.assertIn("my_function", result)

    def test_get_tags_map_without_ctags(self):
        # Create a temporary directory with a sample Python file containing identifiers
        test_file = "test_file_without_ctags.py"
        file_content = """\
class MyClass:
    def my_method(self, arg1, arg2):
        return arg1 + arg2

def my_function(arg1, arg2):
    return arg1 * arg2
"""

        with tempfile.TemporaryDirectory() as temp_dir:
            with open(os.path.join(temp_dir, test_file), "w") as f:
                f.write(file_content)

            repo_map = RepoMap(use_ctags=False, root=temp_dir)
            other_files = [os.path.join(temp_dir, test_file)]
            result = repo_map.get_tags_map(other_files)

            # Check if the result contains the expected tags map without ctags
            self.assertIn("test_file_without_ctags.py:", result)

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

This new test creates a temporary directory with a sample Python file containing a class, a method, and a function. It then checks if the `get_tags_map` function returns the expected tags map containing the file when `ctags=False`.
