[issue4170] segfault with defaultdict and pickle

[Hirokazu Yamamoto]

I created test case referring to test_bytes, but I noticed
range(pickle.HIGHETST_PROTOCOL) doesn't test HIGHEST_PROTOCOL itself. So
patch revised. I created another tracker item for other tests using
range(pickle.HIGHETST_PROTOCOL). See issue4183.
