WIP GH doesn't internalize referenced Breps

attn @DavidRutten - The ability to internalize a referenced Brep appears to be broken in the current WIP of Grasshopper. They appear to maintain their dependence on geometry in the rhino doc - even if they go from “Referenced Brep” to “Closed Brep” if the rhino doc is switched they become null immediately. Possibly related to other serialization problems? Grashopper Rhino WIP internalised Data fails to load in RH5

I take it back - its not a serialization / internalization problem - it’s just that on document context switch (new document) something went funny with the document expiration and it appeared to be empty. the internalized data came back on the next solution. I can’t reproduce the issue consistently so could have just been a ghost!
