QtConcurrent rewrites any exception that doesn't inherit QException into a QUnhandledException, incl. QtTest's internal TestFailedException class (ditto for skipped). At the exit from a test function, QtTest therefore no longer recognizes the exceptions as its own, and lets them escape, or logs them as unexpected. Fix by inheriting the exceptions from QException, but QtConcurrent should really be fixed to use exception_ptr and not rely on Q(Unhandled)Exception. Add a check to tst_selftests. [ChangeLog][QtTest] Fixed a bug which prevented QTEST_THROW_ON_FAIL and QTEST_THROW_ON_SKIP from working with QCOMPARE(), QVERIFY(), and QSKIP() invoked from within QtConcurrent functions.
