    pipeline: disconnect ready tracking after setup
    
    We can't really handle a single pipeline tracking load/unload/load, so
    just disconnect our unload tracking after we have connected.
    
    Instead, we rely on the build manager to reset the pipeline when the
    configuration changes.
