Reproduce in Python doesn't include baseline comparison reforms

[nikhilwoodruff]

e.g. when you're comparing one policy reform against another- the baseline isn't included in the Microsimulation initialisation.

@nikhilwoodruff Is this still the case? And how vital is the fix?

It's still the case: e.g. here the ARPA CTC custom baseline isn't defined https://policyengine.org/us/policy?focus=policyOutput.codeReproducibility&reform=14&region=us&timePeriod=2023&baseline=3826

I wouldn't give this very high priority. Both reproducing in Python and custom baselines are niche uses, and the intersection doubly so.
