bkpr: add payment_id parameter to listaccountevents to filter events.

When you have *lots* of events in your bkpr database looking up a
specific event via calling bkpr-listaccountevents and using jq or
grep to filter gets very slow (and wasteful of CPU and disk resources).
This commit adds the paremeter payment_id to the call to filter for a
specific payment id via a where clause in the request to the database of bkpr.

Changelog-Added: Plugins: Add payment_id parameter to bkpr-listaccountevents to filter events.
