Description

When the unit test tries to validate "finalgrade" with different set of grade max, then it will fail after "test_upgrade_calculated_grade_items_freeze" function in core_testsuite because the static $cache variable does not reset and the "minmaxtouse" collides with previous unit tests.

Steps to reproduce:

Write unit test (attached in MDL-70245-patch.txt) that implement to validate "finalgrade" with different set of grademax (for course category and grade item) after the function "test_upgrade_calculated_grade_items_freeze" .
Run vendor/bin/phpunit --testsuite=core_testsuite

Expected:

Unit tests pass

Actual:

Unit tests fail with unexpected "finalgrade" getting returned (because it is using the previous "minmaxtouse" which is set in the function "test_upgrade_calculated_grade_items_freeze")
