fix bankKeeper initialization steps

[MSalopek]

This PR attempts to fix failing interchain security related e2e tests.

Outline of the issue:

• https://github.com/duality-labs/duality/blob/upgrade-sdk-2/app/app.go#L316

In app.go bankKeeper setup, the module account handling outgoing fees (from consumer to provider) needs to be able to send funds. To enable that it needs to be removed from the blockedAddrs map.

---

This is how it was solved in interchain-security consumerApp:

• https://github.com/cosmos/interchain-security/blob/main/app/consumer/app.go#L272

    // Remove the fee-pool from the group of blocked recipient addresses in bank
    // this is required for the consumer chain to be able to send tokens to
    // the provider chain
    bankBlockedAddrs := app.ModuleAccountAddrs()
    delete(bankBlockedAddrs, authtypes.NewModuleAddress(
        ibcconsumertypes.ConsumerToSendToProviderName).String())

    app.BankKeeper = bankkeeper.NewBaseKeeper(
        appCodec,
        keys[banktypes.StoreKey],
        app.AccountKeeper,
        app.GetSubspace(banktypes.ModuleName),
        bankBlockedAddrs,
    )
