Bills Module get_bill broken when used with period=previous

[ObjectiveWriter]

The problem

According to the docs one can request the last period for a bill (by id) by sending a request to: /api/v0/bills/:id?period=previous

However no useful data is returned.

curl -H 'X-Auth-Token: -removed-' 'http:/192.168.1.244/api/v0/bills/5?period=previous'
{
    "status": "ok",
    "bills": [],
    "count": 0
}

However the API appears to be somewhat working, as the "history" can be requested.

 curl -H 'X-Auth-Token: -removed-' 'http:/192.168.1.244/api/v0/bills/5/history'
{
    "status": "ok",
    "bill_history": [
        {
            "bill_hist_id": 24,
            "bill_id": 5,
            "updated": "2024-04-25 15:01:01",
......

On the testing setup we have various different historic bills for the bill-id5, so there is data of more than one complete billing period.

Any advice would be apreciated.
