ea3beb4f5a Refs #30446 -- Defined default output_field of text database functions. 
This prevented the default behavior of
BaseExpression._resolve_output_field from error'ing out when such
functions accepted both expressions from mixed types
(e.g. SubStr(CharField, IntegerField, IntegerField)).

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.

4d1420947e Fixed #30494 -- Disabled __year lookup optimization for indirect values. 
The previous heuristics were naively enabling the BETWEEN optimization on
successful cast of the first rhs SQL params to an integer while it was
not appropriate for a lot of database resolved expressions.

Thanks Alexey Chernov for the report.
