If one of the mock.patch methods is used with autospec=True on a staticmethod in an object, the mock library determines that it is not callable by checking for the __call__ attribute. This results in a NonCallableMagicMock being returned which of course dies with the following error when the mocked method is called:

TypeError: 'NonCallableMagicMock' object is not callable

It seems that the create_autospec needs to special case for classmethod and staticmethod.

The following change seems to fix it, however I am only vaguely familiar with the internals of mock so I'm not sure what this breaks.
