Problem statement

Description

	(last modified by Mariusz Felisiak)

__isnull should not allow for non-boolean values. Using truthy/falsey doesn't promote INNER JOIN to an OUTER JOIN but works fine for a simple queries. Using non-boolean values is ​undocumented and untested. IMO we should raise an error for non-boolean values to avoid confusion and for consistency.

The environment starts at commit 2f72480fbd27 (django/django 3.1), dependencies installed and tests runnable from the first minute. You are graded by hidden tests taken from the fix that was actually merged upstream.
