Fix a small logging mistake and clean up

clean up

• Use a specific error name for each section of the realizer (see note)
• merge two realizeError conditionals

fix

logging tracking error instead of realize error when the tracking fails

Note

The number of different actions with different errors in #Reconcile feels like a code smell. We're already concerned by the complexity of reconcile so this is not a surprise, just further evidence.

This is not mergable due to realizers getting unified. Will re-implement
