0.6.1 breaks acknowledging messages

[Michael St Clair]

The expected payload should look like this

{
    "ackIds": [
        "projects/genesis-block-testing/subscriptions/test-subscription:72"
    ]
}

but with the upgrade it is sending the ids as maps

{
    "ackIds": [
        {
            "ack_id": "projects/genesis-block-testing/subscriptions/test-subscription:72"
        }
    ]
}
