BUG: Fix argument order in call to super

[eddiejessup]

• tests added / passed
• passes git diff upstream/master | flake8 --diff

super should have arguments (type, object), not (object, type).

I've run test_fast.sh using Python 2.7 and it gives 2 failures relating to language locales (I'm using en_GB). Pretty sure these are unrelated to the commit.

hah I guess we don't have a test for that

can u create a test that hits that path as well

[eddiejessup]

Sure. I could find a concrete sub-class of PandasObject that doesn't implement memory_usage, instantiate that, get its sizeof() and check it returns something of the correct type? For example, from a quick look, looks like the GroupBy class is such a class.

can you rebase / update
