Summary:
See T354. List every rule which has ever been applied in X-Herald-Rules, not
just the ones which most recently triggered.
Also some random fixes while I was debugging this:
- When conduit methods throw non-conduit exceptions, make sure they get
logged.
- Trigger the Facebook "tasks" backcompat block only if we were going to fail
(this should reduce the shakniess of the transition).
- Fix some log spew from the new field stuff.
Test Plan:
- Created a rule (ID #3) "No Zebras" which triggers for revisions without
"zebra" in the title.
- Created a revision without "zebra" in the title, got X-Herald-Rules: <2>,
<3>
- Updated revision to have "zebra" in the title, verified rule did not trigger
in Herald transcript.
- Verified X-Herald-Rules is still: <2>, <3>
