Review comment:
Instead if checking the output here, I could fix this by changing to tag at
to_runner_api() method of ExternalTransform. Reverted this change.

> 'ExternalTransform.expand()' can be used to expand a remote transform and
> build the correct runner-api subgraph for that transform. However currently
> we do not modify the AppliedPTransform sub-graph correctly during this
> process. Relevant code location here.

> Without this, DataflowRunner that relies in this object graph (not just the
> runner API proto) to build the job submission request to Dataflow service
> cannot construct this request properly.
