    foundry: fix unloading of pipeline addins
    
    Addins that were delayed during loading where not unloaded properly because
    we did not have the "HAS_LOADED" data set. Also, force destruction of them
    when the pipeline is unloaded so they are removed from the object tree.
    
    Fixes #1575
