fix: Cleanup redundant batch cleanup mechanisms, improve ListDistinctBatchResources query

[juliusgeo]

Description

2 fixes here:

1. after_v1_task_runtime_delete_cleanup_batch_runtime already cleans up batch runtime rows once the v1_task_runtime rows are cleaned up, which happens before releaseBatchedQueueItems runs, so we don't need to do it twice.
2. Improves the ListDistinctBatchResources so it short circuits on the existence of any v1_batched_queue_item row, rather than accumulating all of them. This should help fix worst case performance so that an accumulation of large numbers of v1_batched_queue_item rows doesn't impact this queries' performance.
