rpcdaemon: nonsystematic failure in ots_searchTransactionsAfter integration test 03

This happened in #2789 [here](https://github.com/erigontech/silkworm/actions/runs/13812585673/job/38637462777?pr=2789) but it is not easily reproducible in debug build. It doesn't seem to be related to the changes in such PR.
