Pathfinder: stop returning more draws than requested #3279

Closed WardBrian closed 7 months ago

WardBrian commented 7 months ago

Submission Checklist

Summary

Closes #3268. Now when the number of draws requested is smaller than the number of draws the ELBO calculations do internally, they are truncated to the expected size rather than all returned.

I also fixed up #3278

Intended Effect

How to Verify

I have a test in another project, I wasn't sure if we wanted to adapt one for here or not.
