    gs-os-update-page: Mark installed apps for removal
    
    When an app exists in the GsOSUpdatePage, it should have been
    created by a plugin with the goal of adding, removing,
    updating or downgrading it. Therefore, if the app is in the
    GS_APP_STATE_INSTALLED, it should be safe for GS to assume that
    the app has to be removed.
    
    An example situation where this is useful is when an package
    upgrade removes a dependency on an OS package and the "dependent"
    package can then be safely removed. This might not be a big
    matter in stable distros, but is definitely something that happens
    often in rolling-release channels.
