    Revert "endSessionDialog: apply updates by default"
    
    Turns out it's not that clear in which cases we want to apply updates
    and in which ones we shouldn't. For example one case is when the device
    is running on battery, where we currently display a warning, but still
    install updates by default.
    
    So let's revert that again for now and hopefully work out a proper
    concept for updates in the future.
    
    This reverts commit ddb85c03c370b481173a92b1a4e1560afdddc9b1.
