Fix DebugEventListener test: remove cache size limit for phase 2

Phase 1 fills the 1MB database with 100K events that may not fully
upload during teardown. Phase 2 reuses the same DB, so the cache file
size limit must be removed to allow new events to be stored. This is
simpler and more robust than using a separate DB path or trying to
delete the file between phases (which races with sqlite3_close_v2).
