    extensionSystem: Fix reloading on version-validation changes
    
    The current code only works for enabled extensions, which means
    that extensions that were marked OUT_OF_DATE cannot be enabled
    without a restart when disabling the version check.
    Fix this by reloading all extensions while making sure to only
    enable any extensions when we're supposed to.
