Problem: The counters used to track the number of unique fingerprints we store in-memory for sql stats were refactored in #110805. In change #110805 a bug was introduced where it incresease the memory instead of resetting the counts. This causes the statstics to stop calculating new stats once the limit is hit. Solution: Fix the bug by resetting the counters instead of increasing them. Added new test to test the reset functionality. Fixes: #111583 Release note (sql change): Fix a bug that causes the sql stats to stop collecting new stats.
