eth/filters: fix pruned history error for genesis block (ethereum#31941)

lunargon · howjmay · commit e162beecc97e · 2025-08-28T01:23:10.000+08:00
Fixes an issue where querying logs for block ranges starting from 0 would fail with an irrelevant
error on a pruned node. Now the correct "history is pruned" error will be returned.
