ClangStaticAnalyzer: Tests: Fix failing runner tests on Windows

Browse Source 
Both runner tests fail on Windows at

	QVERIFY(st.expectStartedSignal());

because QProcess::started() is emitted before ClangStaticAnalyzerRunner::run()
returns and thus before QSignalSpy::wait() is reached.

Watch out for the signal manually before calling run().
