Execute Herald again after promoting revisions out of the "Draft" state
Fixes T13027. Ref T2543. When revisions promote from "Draft" because builds finish or no builds are configured, the status currently switches from "Draft" to "Needs Review" without re-running Herald.
This means that some rules -- notably, "Send me an email" rules -- don't fire as soon as they should.
Instead of applying this promotion in a hacky way inline, queue it and apply it normally in a second edit, after the current group finishes.
- Created a revision, reviewed Herald transcripts.
- Saw three Herald passes:
- First pass (revision creation) triggered builds and no email.
- Second pass (builds finished) did not trigger builds (no update) and did not trigger email (revision still a draft).
- Third pass (after promotion out of 'draft') did not trigger builds (no update) but did trigger email (revision no longer a draft).
