Affiliate Forwarder config not work for values different than zero

[JoaoCampos89]

Set the Affiliate Fee percentage to a value different than zero results in zero value for the affiliate config:

Changing the implementation to this one below works as intended:

But then we can not complete the market buy orders because the computation to get the eth amount required does not take in account the additional eth value needed for the fees, this implementation under src/store/relayer/actions solves the issue:

    const ethBalance = getEthBalance(state) as BigNumber;
            let ethAmountRequired = amounts.reduce((total: BigNumber, currentValue: BigNumber) => {
                return total.plus(currentValue);
            }, new BigNumber(0));

            ethAmountRequired = ethAmountRequired.plus(
                ethAmountRequired.times(new BigNumber(AFFILIATE_FEE_PERCENTAGE)),
            );

            const isEthBalanceEnough = ethBalance.isGreaterThan(ethAmountRequired);
            const isMarketBuyForwarder = isBuy && isWeth(quoteToken.symbol) && isEthBalanceEnough;

Using Asset buyer solves this issue also.
