fix(export-genesis): fix export genesis command for missing values

[Pantani]

part of #1384

Description

Some values are missing in the genesis JSON when we are exporting it. So we can't validate the genesis after export.

Most of the values should be upgraded based on default genesis parameters, but maybe we should also add the liquidityPoolRecords parameter from the liquidity module

@Pantani @glnro this is not tested via the current tests that we have right? If not, is it practical to add something?

It's strange that Name and Symbol were left empty when the rest was populated.
We should ensure whatever it is it matches https://github.com/cosmos/chain-registry/blob/master/cosmoshub/assetlist.json

They have us listed as

        "name": "Cosmos",
        "symbol": "ATOM",

Either we update the chain registry or update here so that name = Cosmos instead of Cosmos Hub Atom.
I prefer the former since there may be wallets, exchanges or explorers using the chain-registry already.
