QmlCppDebugger: Fix transitions if cpp engine fails in setup step
QmlCppDebugger: Fix transitions if cpp engine fails in setup step

is found) in state EngineSetupRequested. In this case the Qml Engine
will be already in state EngineSetupOk ... let it gracefully move to
InferiorSetupFailed via InferiorSetupRequested.
