Fix for pickling exception when deserializing GithubException.

See: https://bugs.python.org/issue9400

"Because CalledProcessError extends PyExc_BaseException, which defines a __reduce__ method, that special method cause the pickle load to call the exception type's __init__ method with packed self.args as arguments. So if a subclass of "Exception" needs to behave correctly in pickling, it should make self.args meet its __init__ method's function signature. "
