Fix unstubbing of __new__

[awestendorf]

This seems to be working. In writing tests for https://github.com/agoragames/torus , it seems that an expectation on the Timeseries type was not cleaned up properly, and resulted in the following error for a test that didn't try to mock out that constructor.

ERROR: test_match_list (test.unit.schema_test.SchemaTest)

Are you finding that this is still an issue, because I'm seeing something similar. I use mock on a static function, and in subsequent tests I see the function is added back to the class as an unbounded function. When I invoke the function in the subsequent tests, I get the same TypeError: unbound method... result.

[awestendorf]

Are you using @staticmethod? If so, I don't think that's a case that's currently tested. Each one of those require some special handling, so likely there needs to be a test written, and then a new StubStatic implementation.

[ajferrick]

Yeah, I was using @staticmethod. Is this something you'd likely be working on soon, or should I explore it myself and PR?

[awestendorf]

@ajferrick This commit 1a3d80c may have what you need, as a staticmethod looks identical to an unbound method in Python3. That may not work specifically with mock, but expect should work so long as you use it in the form expect(obj, 'staticmethod_name').

Sorry for the late response, open source dropped off my radar as we had a very busy end of year.
