Broken test with flake8>=3.9.1

[mweinelt]

After upgrading to flake>=3.9.1 the following test failure came up.

Traceback (most recent call last):
  File "run_tests.py", line 117, in <module>

Seems related to this change: PyCQA/flake8#1317

I suspect we didn't cut a new release that includes the updates to our test suite yet @jparise ?

[jparise]

Our usage of extend_default_ignore was introduced in b562e5a, which has yet to be released in a tagged version. I can do that soon (#172).

... but that doesn't explain the error above, which is for the tagged 0.11.1 release. Is there something backwards-incompatible about flake8's 3.9.1's "extended ignore" implementation?

[sigmavirus24]

I believe our tests mock out things that are internal to Flake8, which I've never liked but it hasn't caused too much trouble. I think the change I made caused those half-mocked things to not have all the detail needed

[sigmavirus24]

6d62db8 is (I believe) what would fix things

[jparise]

I believe this was fixed in the last release. Can you confirm, @mweinelt?

[mweinelt]

Yes, LGTM. Thanks!
