Remove massive "rule applied" query

Summary:
Herald rules may be marked as "one-time". We track this by writing a row with
<ruleID, phid> when we apply a rule.

However, the current test for rule application involves loading every <ruleID,
*> pair. We also always write this row even for rules which are not one-time, so
if there are 100 rules, we'll load 1,000,000 rows after processing 10,000
objects.

Instead, load only the <phid, *> pairs, which are guaranteed to be bounded to at
most the number of rules.
