Purpose

Following PR #9320, this fixes 2 test failures with partial, multi-output custom nodes breaking. This uncovered a bug in the AST creation for such nodes. The extra AST to create a Dictionary in BuildAstForPartialMultiOutput is not required and therefore the base class method need not be overridden in the CustomNodeController. It feels good to fix bugs by removing code :)
