miner: fix nil statedb panic in applyTransaction pre-amsterdam

Browse source 
When accessList is nil (pre-Amsterdam blocks), stateCopy is never
assigned and passed as nil to core.ApplyTransaction. This causes a
nil pointer dereference at state_processor.go:224 when checking
statedb.Database().TrieDB().IsVerkle().

Set stateCopy = env.state in the non-Amsterdam path so
ApplyTransaction always receives a valid statedb.
