This bug is caused by following reason:
(1) when region merge occur, a new stream with new region_worker will be created. Then region_worker.rtsManager will be empty;
(2) if merged region has some fallback prewrite lock in it, the resolvedTs event will fall back last checkpointTs and will be ignored. Then resolve lock logic can't trigger for region_worker.rtsManager has no record for that region.
