Fixed #31106 -- Fixed migrations crash on PostgreSQL 10+ when adding FK constraints inline and changing data. 
This allows adding foreign key constraints inline and changing data in
the same migration on PostgreSQL 10+.

Regression in 738faf9da2.

Thanks Janne Rönkkö for the report and Simon Charette for the
implementation idea and review.

7552de7866 Used more specific unittest assertions in tests. 
* assertIsNone()/assertIsNotNone() instead of comparing to None.
* assertLess() for < comparisons.
* assertIs() for 'is' expressions.
* assertIsInstance() for isinstance() expressions.
* rounding of assertAlmostEqual() for round() expressions.
* assertIs(..., True/False) instead of comparing to True/False.
* assertIs()/assertIsNot() for ==/!= comparisons.
* assertNotEqual() for == comparisons.
* assertTrue()/assertFalse() instead of comparing to True/False.

0b54ab0675 Refs #30033 -- Fixed schema's test_m2m_rename_field_in_target_model test failure on SQLite < 3.20. 
Mixing local test models with non-local models resulted in a referential
integrity error during tear down since the models are removed in separate
schema editor instances which each check constraints.

Failure appeared after 7289874adc.

dba4a634ba Refs #29641 -- Refactored database schema constraint creation. 
Added a test for constraint names in the database.

Updated SQLite introspection to use sqlparse to allow reading the
constraint name for table check and unique constraints.

9f7772e098 Fixed #28884 -- Fixed crash on SQLite when renaming a field in a model referenced by a ManyToManyField. 
Introspected database constraints instead of relying on _meta.related_objects
to determine whether or not a table or a column is referenced on rename
operations.

This has the side effect of ignoring both db_constraint=False and virtual
fields such as GenericRelation which aren't backend by database level
constraints and thus shouldn't prevent the rename operations from being
performed in a transaction.

Regression in 095c1aaa89.

Thanks Tim for the additional tests and edits, and Mariusz for the review.
