> In case a split finds that previous sub-shards exist in construction or recovery state.
it tries to clean them up by invoking deleteshard API. However, the clean up logic tries to
invoke deleteshard on the same sub-shards as many times as the requested number of sub-ranges.
Such repeat calls to deleteshard fail and therefore fail the entire shard split operation.
