    Set the loading state when initializing the UI
    
    The loading-state is necessary to make sure that plugins are correctly
    refreshed when GNOME Software is launched, as it is in refresh time that
    usually plugins load their app catalogs and other resources needed
    during their regular use.
    However, currently only the normal activation (on CLI options) of the
    GNOME Software is calling this loading-state. As a result, options
    like --details and --install are not working.
    
    To fix that, these changes move the call for the loading-state to the
    function that intializes the UI. Since all of the CLI options initialize
    the UI, then we make sure that the loading-state is called for every
    option.
