[2.0.x] Refs #27985 -- Reallowed using __exact=None as an alias for
__isnull=True if a custom lookup class with lookup_name != None is
registered as the exact lookup.
Regression in 58da81a5a372a69f0bac801c412b57f3cce5f188 and prerequisite
for refs #28896.
Backport of 10bfa876be59feec24bb6a40fa11bece808ee405 from master
