[FIX] core: log error on addSubTest

Since #34996, in some case, the error detail was not logged keeping
only the final summary "x errors, x failures" when running TestSuite.

Making fail test test_cache_invalidation for instance won't show
a detailed message when breaking test_01_project_tour will.
This issue occurs when using subtest, like with assertQueryCount,
@users decorator, test_all_l10n, and test_youtube_urls.

Since Testresult addSubTest append directly to error and failures
instead of calling addError and addFailure, we need to ovewrite
addSubtest too.
