Various fixes: * Fix handling of HTTP redirects (avoiding crashes... I hope) * Fix failure to delete FFT models when a feature extraction model transformer was abandoned (also a cause of crashes in the past) * Fix deadlock when said transform was abandoned before its source model was ready because the session was being cleared (and so the source model would never be ready)
