fix: intermittent failures in feature_governance.py (#5868) 
## Issue being fixed or feature implemented
Should fix failures like
https://gitlab.com/dashpay/dash/-/jobs/6107697452

## What was done?
See inline comments

## How Has This Been Tested?
Run lots of `feature_governance.py` in parallel multiple times

## Breaking Changes
n/a
