unintentionally changed the flag's value in 1.9. The null flag for
ManyToManyField isn't that well specified to begin with (does it mean can
the joins generate NULL values (True), or can the returned list be None
(False)?). But I don't see any reason to change the flag's value in 1.9,
so fix for the upcoming 1.9 release seems appropriate.
