Fix a potential crash SimpleAudioEngineOpenSL::playEffect
Fix a crash in SimpleAudioEngineOpenSL::playEffect which would occur when OpenSLEngine::preloadEffect returned FILE_NOT_FOUND. In the case where the sound fails to preload, we should not attempt to call OpenSLEngine::setEffectLooping on that sound.
