Get incomplete results when creating trove instance with replica_count

[Liu Yang]

When I create two replica instances(use `"replica_count": 2`), the response contains only one instance.

e.g.

request:
POST http://25.0.0.179:8779/v1.0/0cbb58a3a7fd4c1d89e4a5f3b8cc0c76/instances
{
    "instance": {
        "name": "slave",
        "flavorRef": 6,
        "replica_count": 2,
        "volume": {
            "type": null,
            "size": 1
        },
        "datastore": {
            "version": "5.5",
            "type": "mysql"
        },
        "replica_of": "839e0bbe-342c-4650-ab05-4323f2473246"
    }
}

response body:

The result contains only slave-2 and no slave-1, in my option, it's should be contain two. although the two replica instance is created successfully.

I have just tried to create two replica instances and it success. Maybe we need log information to see the problem

I have restored this situation, it does exist. But I also noticed that our troveclient test was this way:
https://github.com/openstack/python-troveclient/blob/master/troveclient/tests/test_v1_shell.py#L351

So I am not sure if this is a bug, or a naming error caused by the problem... Will continue to look at the code

Update again, I have two instances here.
