Use presentationLoaded to hide splash screen in HomeAutomation

    
    Replace presentationReady use with presentationLoaded due to changes in
    OpenGL RT signaling. presentationReady indicates that the presentation is
    fully built up (and visible), which is not the case in HomeAutomation
    loader-based code.
