Log Message:
-----------
[1.4.x] Fixed #18823 -- Ensured m2m.clear() works when using through+to_field
There was a potential data-loss issue involved -- when clearing
instance's m2m assignments it was possible some other instance's
m2m data was deleted instead.
This commit also improved None handling for to_field cases.
Backpatch of 611c4d6f1c24763e5e6e331a5dcf9b610288aaa8
