Can't pickle MagicMock or Mock

See original GitHub issue

This is because a MagicMock instance has a custom MagicMock subclass.

{{{
>>> from pickle import dumps
>>> from mock import MagicMock
>>> dumps(MagicMock())
Traceback (most recent call last):
  ...
pickle.PicklingError: Can't pickle <class 'mock.MagicMock'>: it's not the same 
object as mock.MagicMock
}}}

This works for my use case:

class PickableMock(Mock):
    def __reduce__(self):
        return (Mock, ())
