    plugins/flatpak: order before icons plugin so icons are loaded
    
    Because we re-use code from the appstream plugin, locally-installed Flatpaks
    which are loaded from the local AppStream file don't get their pixbuf loaded
    unless the icons plugin is run after Flatpak, which means they are considered
    invalid and not reliably shown in the Installed tab.
