aider: Added a test for the cmd_drop method with glob patterns in the TestCommands class.

# Context:
USER: add a test for that
ASSISTANT: To add a test for the `cmd_drop` method with glob patterns, we need to modify the `tests/test_commands.py` file.

Here's the step-by-step process:

1. Add a new test method `test_cmd_drop_with_glob_patterns` in the `TestCommands` class.
2. In this method, initialize the `Commands` and `InputOutput` objects.
3. Add some files to the chat session.
4. Call the `cmd_drop` method with a glob pattern.
5. Check if the correct files have been removed from the chat session.

Here's the code change:

```python
tests/test_commands.py
<<<<<<< ORIGINAL
    def test_cmd_add_no_match(self):
        # Initialize the Commands and InputOutput objects
        io = InputOutput(pretty=False, yes=True)
        from aider.coders import Coder

        coder = Coder.create(models.GPT35, None, io, openai_api_key="deadbeef")
        commands = Commands(io, coder)

        # Call the cmd_add method with a non-existent file pattern
        commands.cmd_add("*.nonexistent")

        # Check if no files have been added to the chat session
        self.assertEqual(len(coder.abs_fnames), 0)

    def test_cmd_add_no_match(self):
        # Initialize the Commands and InputOutput objects
        io = InputOutput(pretty=False, yes=True)
        from aider.coders import Coder

        coder = Coder.create(models.GPT35, None, io, openai_api_key="deadbeef")
        commands = Commands(io, coder)

        # Call the cmd_add method with a non-existent file pattern
        commands.cmd_add("*.nonexistent")

        # Check if no files have been added to the chat session
        self.assertEqual(len(coder.abs_fnames), 0)

    def test_cmd_drop_with_glob_patterns(self):
        # Initialize the Commands and InputOutput objects
        io = InputOutput(pretty=False, yes=True)
        from aider.coders import Coder

        coder = Coder.create(models.GPT35, None, io, openai_api_key="deadbeef")
        commands = Commands(io, coder)

        # Add some files to the chat session
        commands.cmd_add("*.py")

        # Call the cmd_drop method with a glob pattern
        commands.cmd_drop("*.py")

        # Check if the Python files have been removed from the chat session
        self.assertNotIn(os.path.abspath("test1.py"), coder.abs_fnames)
        self.assertNotIn(os.path.abspath("test2.py"), coder.abs_fnames)
