Fixed __eq__ for windows.

[m1guelperez]

for window in session.list_windows():
    if window.name == "test_window":
        target_window = window
        break
    if target_window == None:
        target_window = session.new_window(
            attach=True, window_name="test_window"
        )

This code failed before at if target_window == None because comparison for windows was implemented like that:

def __eq__(self, other: object) -> bool:
      assert isinstance(other, Window)
      return self.window_id == other.window_id

However, the assert seems a bit off since it is a way to strong assumption. Thus I changed it to:

def __eq__(self, other: object) -> bool:
    if not isinstance(other, Window):
        return False
    return self.window_id == other.window_id

This code now properly returns False when we compare a window with == and the condition is indeed False.

Actually, I would try to avoid negations with not and express the code like this:

def __eq__(self, other: object) -> bool:
    if isinstance(other, Window):
        return self.window_id == other.window_id
    return False

Just my two cents.
