Summary:
Fixes T12302. Currently, we aren't merging multiple "AddAuditors" transactions correctly.
This can occur when Herald triggers multiple auditor rules.
Instead, merge them.
Test Plan:
- Wrote two different Herald rules that add auditors.
- Pushed a commit which triggered them.
- After the change, saw all the auditors get added correctly.
