Droplet list endpoint not directly list droplet that just been created from successful create droplet endpoint.

The droplet not listed in the droplets list response even after successful request to create droplet endpoint.
Request using pydo
```python
droplets = client.droplets.create({
"name": "xxx",
"region": "nyc1",
"size": "xxx",
"image": "xxx",
...
```

Response
```json
{"droplet": {"id": 1234567,
"name": "xxxxxx",
"memory": 245760,
"vcpus": 20,
"disk": 720,
...
"status": "new",
...
}}
```

But in the list it show 0 containers with the name
```json
{"droplets": [], "links": {}, "meta": {"total": 0}}
```
After couple of seconds then it actually listed

```json
{"droplets": [{"id": 123456789,
"name": "xxxxxx",
"memory": 245760,
"vcpus": 20,
"disk": 720,
...
"status": "new",
...
}]}
```
