Reset translation in test tearDown

[richardebeling]

Fixes order-dependent tests (as caused failure in https://github.com/e-valuation/EvaP/actions/runs/11331145512/job/31510516990)

This still misses tests like class TestStudentIndexView(WebTestWith200Check): (found by searching for class Test)

The second failure with seed 7524442357 still breaks on my machine, now even with two tests failing. Maybe we can use https://github.com/asottile/detect-test-pollution ?

The second failure with seed 7524442357 still breaks on my machine, now even with two tests failing.

The problem was that django.test.TestCase.tearDown doesn't call super.tearDown(), so with inheritance order class TestCase(django.test.TestCase, MyTearDownMixin), the tearDown method of the mixin is never called. Fixed it by swapping the order. ./manage.py test --keepdb --shuffle 7524442357 now works for me.

output of rg "def tearDown":

evap/staff/tests/test_views.py
2379:    def tearDown(self):

evap/evaluation/tests/tools.py
33:    def tearDown(self):

evap/grades/tests.py
54:    def tearDown(self):

only evap/evaluation/tests/tools.py calls super().tearDown(), should we add those to the other two?

Another seed fixed by this PR 1773734012 :)
