    Allow web apps to be in UNAVAILABLE state
    
    After a web app is uninstalled in Software, it is only re-installable if
    it is present in the AppStream data. Otherwise the app must have been
    installed via Epiphany, and the information needed to re-install it
    (e.g. the icon) is not available. If we leave the state as
    GS_APP_STATE_UNKNOWN after the removal, the user is greeted by an ugly
    message "Unable to find org.gnome.Epiphany.WebApp_...." in place of the
    details page. So set the state to GS_APP_STATE_UNAVAILABLE instead, and
    update other parts of Software to allow that state to mean "Don't show
    any Install/Remove/Open button" when it is set on a web app.
