"Starting Erigon on Ethereum mainnet" message in Hive tests

[yperbasis]

Hive tests use the init to save a dev chain genesis + config into the DB. As Barnabas reported, later erigon, when started against such DB instance, incorrectly says that it's starting on Ethereum mainnet:

[INFO] [05-22|14:00:17.201] Initialised chain configuration          config="{ChainID: 3151908, Homestead: 0, DAO: <nil>, Tangerine Whistle: 0, Spurious Dragon: 0, Byzantium: 0, Constantinople: 0, Petersburg: 0, Istanbul: 0, Muir Glacier: <nil>, Berlin: 0, London: 0, Arrow Glacier: <nil>, Gray Glacier: <nil>, Terminal Total Difficulty: 0, Merge Netsplit: 0, Shanghai: 0, Cancun: 0, Prague: 40116386478, Osaka: <nil>, Engine: unknown}" genesis=0x67215f968956398a7268417d063d4c4a6647fd61f474ce101aeb5dd4729ad868
[INFO] [05-22|14:00:17.204] Initialising Ethereum protocol           network=3151908

Apparently that's a bit that was missed by PRs #9408 & #10406.
