    gs-details-page: Reload the page only when the app is idle
    
    It doesn't look good when the user installs/removes an app from the details page
    and the page is reloading in the middle of the install/remove process. This can
    be seen for example with flatpaks, when the applications installs also its
    runtime. There are issued several reload requests, after each installed
    part of the app or the runtime (the runtime, the locale part, the app itself).
    
    The reload can lost track of the install progress too, when it gets a different
    app instance during the reload.
    
    Closes https://gitlab.gnome.org/GNOME/gnome-software/-/issues/1510
