feat(trollbot): improve query perf

[ben-pr-p]

Description

This improves the performance of get_trollbot_matches by only running a ts_query for each token if we have already determined that the message matches at least one token for that stemming mode.

Motivation and Context

We think the long running query times of trollbot may have been negative impacting some other queries, particularly delivery report handling.

How Has This Been Tested?

Running the query directly on production - just a select.
