GitAuto: TypeError 'NoneType' object is not iterable

[gitauto-for-dev]

Resolves #31

Why the bug occurs

The TypeError: 'NoneType' object is not iterable occurs in the filter_my_comments function within comment_manager.py at line 42. This happens because the function attempts to iterate over a None value, likely returned due to a failed API call or missing data.

How to reproduce

1. Trigger the filter_my_comments function in comment_manager.py under conditions where the expected data is None.
2. Observe the TypeError when the function tries to iterate over the None value.

Where / How to code and why

To fix the bug, update the filter_my_comments function in comment_manager.py to handle cases where the data is None. Implement a check to ensure that the data is iterable before attempting to iterate over it. Additionally, enhance the error handling for API calls to prevent None from being returned unexpectedly.

This ensures that the function handles unexpected None values gracefully, adhering to robust coding practices and preventing runtime errors.
