Invalid gindex calculation

2

**Describe the bug** ```ts import {ssz} from "@lodestar/types"; const {BeaconState} = ssz.phase0; console.log( BeaconState.getPathInfo(["validators", 0, "activationEpoch"]).gindex === BeaconState.getPathInfo(["validators", 0, "pubkey"]).gindex ); // true ``` **Expected behavior** `false`
