Stop accessing None as a dictionary
d18ad29 
PyMapping_HasKeyString does not work on None
Accidentally, it used to return false result on silent errors.

Since Python 3.13, this is what happens instead:

    >>> import pylibmc
    >>> m = pylibmc.Client(["10.0.0.1"], binary=True)
    Exception ignored in PyMapping_HasKeyString(); consider using PyMapping_HasKeyStringWithError(), PyMapping_GetOptionalItemString() or PyMapping_GetItemString():
    Traceback (most recent call last):
      File "/usr/lib64/python3.13/site-packages/pylibmc/client.py", line 142, in __init__
        super().__init__(servers=translate_server_specs(servers),
    TypeError: 'NoneType' object is not subscriptable
    ...
    Exception ignored in PyMapping_HasKeyString(); consider using PyMapping_HasKeyStringWithError(), PyMapping_GetOptionalItemString() or PyMapping_GetItemString():
    Traceback (most recent call last):
      File "/usr/lib64/python3.13/site-packages/pylibmc/client.py", line 142, in __init__
        super().__init__(servers=translate_server_specs(servers),
    TypeError: 'NoneType' object is not subscriptable

When this is run via pytest, it leads to:

    pytest.PytestUnraisableExceptionWarning: Exception ignored in PyMapping_HasKeyString(); consider using PyMapping_HasKeyStringWithError(), PyMapping_GetOptionalItemString() or PyMapping_GetItemString(): None
