When doing a basic order twice a misleading error message is given: OrderPartiallyFilled().
Context: OrderValidator.sol#L48-L74, Verifiers.sol#L102-L139
When doing a basic order, the function _validateBasicOrderAndUpdateStatus() is called, which uses _verifyOrderStatus() to verify the order hasnt been used before. After this function it sets _orderStatus[orderHash].numerator = 1; to indicate the orderHash has been used.
When trying to reuse the same order, _verifyOrderStatus() correctly reverts. However it uses the revert message OrderPartiallyFilled() which is not correct because the order has been fully filled before.
Consider giving a different error message in _verifyOrderStatus() when a basic order is executed twice.
