Fix kucoin order status.
When I query a kucoin order after creating it, this is the result:
```
{
"info": {
"coinType": "ETH",
"dealValueTotal": 0,
"feeTotal": 0,
"userOid": "5a7ae81903d6440e9981c7b4",
"dealAmount": 0,
"coinTypePair": "USDT",
"type": "BUY",
"orderOid": "5b35c6579350c87d96523742",
"createdAt": 1530250839000,
"dealOrders": {
"total": 0,
"firstPage": true,
"lastPage": false,
"datas": [],
"currPageNo": 1,
"limit": 20,
"pageNos": 1
},
"dealPriceAverage": 0,
"orderPrice": 410.867406,
"pendingAmount": 1.2393974
},
"id": "5b35c6579350c87d96523742",
"timestamp": 1530250839000,
"datetime": "2018-06-29T05:40:39.000Z",
"lastTradeTimestamp": null,
"symbol": "ETH/USDT",
"type": "limit",
"side": "buy",
"price": 410.867406,
"amount": 1.2393974,
"cost": 509.22799474114447,
"filled": 0,
"remaining": 1.2393974,
"status": "open",
"fee": {
"cost": 0,
"rate": null,
"currency": "ETH"
},
"trades": []
}
```
And this is the order status after canceling it:
```
{
"info": {
"coinType": "ETH",
"dealValueTotal": 0,
"feeTotal": 0,
"userOid": "5a7ae81903d6440e9981c7b4",
"dealAmount": 0,
"coinTypePair": "USDT",
"type": "BUY",
"isActive": false,
"orderOid": "5b35c6579350c87d96523742",
"createdAt": 1530250839000,
"dealOrders": {
"total": 0,
"firstPage": true,
"lastPage": false,
"datas": [],
"currPageNo": 1,
"limit": 20,
"pageNos": 1
},
"dealPriceAverage": 0,
"orderPrice": 410.867406,
"pendingAmount": 1.2393974
},
"id": "5b35c6579350c87d96523742",
"timestamp": 1530250839000,
"datetime": "2018-06-29T05:40:39.000Z",
"lastTradeTimestamp": null,
"symbol": "ETH/USDT",
"type": "limit",
"side": "buy",
"price": 410.867406,
"amount": 1.2393974,
"cost": 509.22799474114447,
"filled": 0,
"remaining": 1.2393974,
"status": "open",
"fee": {
"cost": 0,
"rate": null,
"currency": "ETH"
},
"trades": []
}
```
Note that the `info` dict does not contain any `status` key. The first response contains no status information it seems. The second one has an `isActive=false` flag.
I changed the way we are reading the status then.
