3a1863319c [4.2.x] Fixed #34754 -- Fixed JSONField check constraints validation on NULL values. 
The __isnull lookup of JSONField must special case
Value(None, JSONField()) left-hand-side in order to be coherent with
its convoluted null handling.

Since psycopg>=3 offers no way to pass a NULL::jsonb the issue is
resolved by optimizing IsNull(Value(None), True | False) to
True | False.

Regression in 5c23d9f0c3.

Thanks Alexandre Collet for the report.

This will notably silence the warnings issued when running the test
suite on MySQL and MariaDB.

9142bebff2 Refs #11964 -- Changed CheckConstraint() signature to use keyword-only arguments. 
Also renamed the `constraint` argument to `check` to better represent which
part of the constraint the provided `Q` object represents.
