[3.0.x] Fixed #31071 -- Disabled insert optimization for primary keys with defaults when loading fixtures.
Model.save_base() is called directly when loading fixtures and assumes
existing rows will be updated. Branching of "raw" allows to maintain
the optimization introduced in #29260 while supporting this edge case.
Regression in 85458e94e38c20e57939947ee515a1a53689659f.
Thanks Reupen Shah for the report.
Backport of 5779cc938a34eb96815c7a40ded2c8f6c8087c58 from master
