UI logs for multi-step workflows with templateRef still missing in v3.2.1

[kruegener]

Summary

Version 3.2.0 introduced a bug regarding logs in the UI for multi-step workflows #6947.
This was mostly fixed with version 3.2.1 via #6925, however some edge cases still fail.

In our case, a step using templateRef still does not work. The pod name in the UI for this step contains undefined, where according to the new pod naming scheme the step name should be.
The same config used to work in 2.x.x and 3.1.8.

The workflow actually runs the step/pod completely ok, just the logs are still missing.

some nodes have undefined in the pod name causing query the backend using incorrect url

Hi @JPZ13 , can you have a look into this as well

[JPZ13]

Yes. I'll incorporate into #6982

[JPZ13]

@kruegener and @tczhao - are there any other notable edge cases you're seeing? I'll add specific tests for each case y'all call out

[kruegener]

So far just the templateRef in a multi-step workflow in our case. Will update if there's more. Thanks for fixing it ;)
