Return default from hash client when using positional argument

[Pankrat]

When using HashClient with ignore_exc, get would always return
None if no server is available and the default is passed as a
positional argument. The other clients return the default
value in this case. An earlier fix only had the desired effect when
passing default as a keyword argument.

For example, Django passes the default as a positional argument.

Return the default value so HashClient behaves like the other
clients even when using

Fixes another variation of issue #350

This should probably be changed to "Unreleased". I just put the version from `pymemcache/__init__.py` there as it looked like this is going to be the upcoming version. Joe Gordon ***@***.***> schrieb am Do., 7. Okt. 2021, 22:02:

Thanks @Pankrat!

@Pankrat Just curious if it's better to keep the function parameters (declaration) consistent and have something like :

    def get(self, key, *args, **kwargs):
        if 'default' in kwargs:
            default = kwargs.get('default')
        elif args:
            default = args[0]
        else:
            default = None
        return self._run_cmd('get', key, default, *args, **kwargs)

as opposed to

    def get(self, key, default=None, **kwargs):
