fix: fix miss makezero bug

[alingse]

I was running github actions to run linter makezero for top github golang repos.

see issues alingse/go-linter-runner#1

and the github actions output https://github.com/alingse/go-linter-runner/actions/runs/9242658341/job/25425755939

====================================================================================================
append to slice `newPending` with non-zero initialized length at https://github.com/cube2222/octosql/blob/main/outputs/stream/internally_consistent_output_stream_wrapper.go#L2[9](https://github.com/alingse/go-linter-runner/actions/runs/9242658341/job/25425755939#step:4:10):18
====================================================================================================

but the newPending pending convert is complex to understand, maybe this was a feature ?
