Fix NoneType Error in getActiveWindowTitle Check

Problem

When running Selenium tests on Windows, we encountered an issue where pyautogui.getActiveWindowTitle() occasionally returns None. This causes the code to crash with a NoneType error because the subsequent startswith() method cannot be called on a None value.

This typically happens when:

• The window focus is temporarily lost
• The system is under heavy load
• Multiple windows are being managed simultaneously

Solution

Added a fallback to empty string using Python's or operator:

py_a_g_title = pyautogui.getActiveWindowTitle() or ""

This ensures that:

1. If getActiveWindowTitle() returns a valid title, it will be used
2. If it returns None, an empty string will be used instead
3. The startswith() check can safely proceed in all cases

The fix prevents test failures due to window management issues and improves stability of Selenium tests on Windows, with no impact on existing functionality when window titles are properly returned.

Verified the fix by running the test suite on Windows, specifically checking scenarios where window focus might be lost or changed rapidly.

Also, I've been moving toward the principles outlined in https://github.com/readme/featured/how-open-is-open-source:
"Open-Source, not Open-Contribution" (with some special exceptions).

My bad I didn’t checked that it’s not Open for contributions, still thank you for fixing that.
