(stable) Fix issue with "Publish/Notify" handling in repositories
That change primarily focused on the "spammy junk during import" issue, and the code did get the importing flag right. It looks like my testing in D11827 focused on "during import" and just missed this case.
Test Plan: Grepped for disable-herald. Grepped for herald-disable.
