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

lunargon · web-flow · commit 778430a689af · 2025-06-03T17:13:35.000+02:00
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.
