Fixed #21102 -- pickling a QuerySet with prefetches twice
...
Fixed the bug that a QuerySet that prefetches related objects cannot be
pickled and unpickled more than once (The second pickling attempt
raises an exception).
Added a new test for the queryset pickling idempotency.
The bug was introduced by

[1.5.x] Fixed prefetch_related + pickle regressions
...
There were a couple of regressions related to field pickling. The

The regressions aren't present in master, the fix was likely in
f403653cf1Fixed #20157 , fixed #20257 . Also made QuerySets with model=None
