    extensionSystem: Fix updating extension list on session update
    
    Before reenabling all extensions, we update the list of enabled extensions
    to catch any changes that happened while extensions were enabled. However
    this is currently broken as onEnabledExtensionsChanged() is a nop while
    disabled, so just call getEnabledExtensions() directly.
