Small change to Streamer in TFCSParametrizationChain to prevent premature object deletion
Changed one get to a release.
Retained the components being written by the streamer for the lifetime of the parent object (or until the streamer is called again). Improved approach on advice of review. There is a unique pointer that goes out of scope, and I think it's taking some data with it. This causes me issues in !63562 (merged)
