Remove a couple noisy errors from linter

Removing:
E128 continuation line under-indented for visual indent
F403 'from test_filters import *' used; unable to detect undefined names

Feel free to object and/or add more.
What is `F403`? I can't find it on that page.

Ah, google says it's about `from xyz import *`. I think people should be shamed for * imports.
