Missing function call `()` leads to:
TypeError: descriptor '__init__' of 'super' object needs an argument

While deferring many-to-many and GFK has no effect, the previous
implementation of QuerySet.defer() ignore them instead of crashing.

Thanks Paco Martínez for the report.
Special thanks to Hannes Ljungberg for finding multiple implementation
gaps.
Thanks also to Simon Charette, Adam Johnson, and Mariusz Felisiak for
reviews.
Proper escaping of % in string literals used when defining constaints
was attempted (a8b3f96f6) by overriding quote_value of Postgres and
Oracle schema editor. The same approach was used when adding support for
constraints to the MySQL/MariaDB backend (1fc2c70).
Later on it was discovered that this approach was not appropriate and
that a preferable one was to pass params=None when executing the
constraint creation DDL to avoid any form of interpolation in the first
place (42e8cf47).
When the second patch was applied the corrective of the first were not
removed which caused % literals to be unnecessary doubled. This flew
under the radar because the existings test were crafted in a way that
consecutive %% didn't catch regressions.
This commit introduces an extra test for __exact lookups which
highlights more adequately % doubling problems but also adjust a
previous __endswith test to cover % doubling problems (%\% -> %%\%%).
Thanks Thomas Kolar for the report.

This ensures that constraint violations are tested in isolation from
each other as an IntegrityError only ensures a least one constraint is
violated.
For example, the assertion added in 42e8cf4 break both the
name_constraint_rhs and the rebate_constraint constraints and thus
doesn't constitute a proper regression test. Refs #32369.

This also reverts commit 1e4da439556cdd69eb9f91e07f99cf77997e70d2.
This makes squashing migrations an available path for changing
Meta.index_together, which is deprecated, to Meta.indexes.

QuerySet.update_or_create() uses nested atomic to handle possible
integrity errors taking savepoints as way to mark back the connection
as usable. Savepoints are not returned when
uses_savepoints/can_release_savepoints feature flags are set to False.
As a consequence, QuerySet.update_or_create() assumed the outer atomic
block is tainted and raised TransactionManagementError.
This commit partly reverts 331a460f8f2e4f447b68fba491464b68c9b21fd1.
Thanks gatello-s for the report.
