bug (4.2.0): New __del__ method in transport.py

[daaniam]

The version of zeep: 4.2.0

After the upgrade from 4.1.0 > 4.2.0 there is an error following each successful request:

Exception ignored in: <function Transport.__del__ at 0x7f9d829c7c40>
Traceback (most recent call last):
  File "/usr/local/lib/python3.11/site-packages/zeep/transports.py", line 159, in __del__
    if self.__close_session:
       ^^^^^^^^^^^^^^^^^^^^
AttributeError: 'AsyncTransport' object has no attribute '_Transport__close_session'

There is no self.__close_session on AsyncTransport class.

Thanks for you work!
