    [Flatpak] Save passwords in libsecret with the same prefix as used by D-Bus services
    
    As the passwords are saved in the host system, the eds-origin key cannot
    use the same value as the host system, because otherwise the secret-monitor
    module of evolution-source-registry would delete the password, because
    the ESource is unknown to it. Similarly the other way around, the inner
    (in Flatpak) source registry would delete system passwords, because those
    ESource-s are unknown to it.
