    client: Strip remote dbus error when setting metadata fails
    
    Without this, if the function fails, the error presented to the user looks
    like:
    
    GDBus.Error:org.gtk.GDBus.UnmappedGError.Quark._g_2dio_2derror_2dquark.Code1:
    Can't find metadata file /home/ross/.local/share/gvfs-metadata/home
