actualSamples is not added when allPages is equal to True in scalardata service

[kan-fu]

allPages=True in scalardata services can concatenate data from multiple pages. However the actualSamples is not summed.

Steps to reproduce:

1. Run the code snippet below. Without "rowLimit", the json should return 60 files.

   params = {
   "deviceCode": "BPR-Folger-59",
   "dateFrom": "2019-11-23T00:00:00.000Z",
   "dateTo": "2019-11-23T00:01:00.000Z",
   "rowLimit": 25,
   }
   data = onc.getDirectByDevice(params, allPages=True)
   data["sensorData"]

   Expected behavior:

• actualSamples should be 60.

Actual behavior:

• actualSamples is 25 (it returns the value from querying the first page)
