    flatpak: Set the correct origin when installing a flatpakref
    
    When installing a flatpakref, part of the process is to install its
    ref file, and the code was assuming that this installation always
    results in a new remote (named as app_name-origin). However, if there
    is already a remote with the same URI as the one coming from the ref
    file, it will not add the new one in order to avoid redudancy.
    
    Since the GsApp representing the one in the flatpakref was being
    assigned the "app_name-origin" as its origin, it would fail to install
    later because this expected origin may not exist (as explained above).
    
    To fix this, once the ref file is installed, we get the resulting
    remote's name (i.e. a new one or the existing one) and override the
    app's origin with it, which will allow the installation to succeed.
