Removing redundant check if creditFee isUnsignedInteger, because creditFee is an optional field in the subtxcloseaccount payload and if it is not set then it will be set to 0 in the special tx payload. Which in turn will cause an error in the utils.isUnsignedInteger check. Removing it is save because the field has already been checked if it's being a number
