bug(evm): de-synchronization between wasm bank balance and EVM account state

[k-yang]

Description

Transfer between regular base account and an account made from a Wasm contract

Steps to Reproduce

1. bank send funds to a wasm account

nibid tx bank send \
nibi1zaavvzxez0elundtn32qnk9lkm8kmcsz44g7xl \
nibi14hj2tavq8fpesdwxxcu44rty3hh90vhujrvcmstl4zr3txmfvw9ssa9gcs \
1000000unibi \
--gas auto \
--gas-adjustment 1.5 \
--gas-prices 0.025unibi \
--yes | jq

2. query bank balances

nibid q bank balances nibi14hj2tavq8fpesdwxxcu44rty3hh90vhujrvcmstl4zr3txmfvw9ssa9gcs | jq
{
  "balances": [
    {
      "denom": "unibi",
      "amount": "1000000"
    }
  ],
  "pagination": {
    "next_key": null,
    "total": "0"
  }
}

3. query evm account

nibid q evm account nibi14hj2tavq8fpesdwxxcu44rty3hh90vhujrvcmstl4zr3txmfvw9ssa9gcs | jq
{
  "balance": "0",
  "balance_wei": "0",
  "code_hash": "0xc5d2460186f7233c927e7db2dcc703c0e500b653ca82273b7bfad8045d85a470",
  "nonce": "0",
  "eth_address": "0x5A8D648DEE57b2fc90D98DC17fa887159b69638b",
  "bech32_address": "nibi14hj2tavq8fpesdwxxcu44rty3hh90vhujrvcmstl4zr3txmfvw9ssa9gcs"
}

The EVM account should have the same balance as the bank balance.

Note that this is not related to any difference of actual funds. The GRPC query is simply retrieving the balance incorrectly by using StateDB.GetAccount instead of the bank balance query.
