NNXSW-1697 Remove use of SubgraphView that may become invalid.
The mainSubgraph variable held references to layers in the optimised
graph that become invalid when a graph substitution is made.
The fix is to always use the optimised graph itself rather than a
view of it. The view served no purpose anyway.
