Outdated Transform.Inputs values when chaining expanded transforms

For:
  pcol := ...
  tmp := beam.CrossLanguage(..., {"foo": pcol}, ...)
  out := beam.CrossLanguage(..., {"bar": tmp}, ...)

In the result model pipeline, the second expanded transform's inputs may hold a map from local name to the original PCollection/node ID, even if the first expansion has changed the output IDs.

Looks like a fix is to move the output name remapping after mergeExpandedWithPipeline: https://github.com/apache/beam/blob/928da54e1a95219bfbfa420fbf9c8fb5514fd683/sdks/go/pkg/beam/core/runtime/graphx/translate.go#L160-L163
