QTest is missing a cleanup function to recover from uncaught exceptions

If an uncaught exception occurs during QTest::runTests(), QTestCase, a custom exception handler can not clean up after self. Continuing with additional test runs causes an assertion:

QFATAL : ::UnknownTestFunction ASSERT !currentTestObject in qtestcase.cpp line 1160

The custom handler needs to call a cleanup function, something like [derived from qtestcase.cpp]

QTestResult::finishedCurrentTestFunction();
QTestResult::setCurrentTestFunction(0);
QTestTable::clearGlobalTestTable();
QTestLog::stopLogging();
currentTestObject = 0;
