[Migration] Error when sorting data after sending track event with existing user's info.

Description

Precondition:
A "demo" user (demo@email.com) has tracking and profile in the store (data is created from version 1.6)

Steps to reproduce

1. Send track event with information data.

POST
{
  "user": {
    "name": "demo",
    "email": "demo@email.com",
    "information": {
    "Picture": "demo",
        "Website": "website.com",
        "StreetAddress": "demo",
        "Phone": "123456",
        "Mobile": "123456",
        "City": "demo",
        "State": "demo",
        "ZipCode": "123456",
        "JobTitle": "demo",
        "Company": "demo",
        "Country": "UK",
        "InferredCountry": "UK",
        "Email": "demo@email.com"
    }
  },
  "payload": {
  
  },
  "deviceId": "demo@email.com",
  "eventType": "demo",
  "value": "demo",
  "pageUri": "demo",
  "pageTitle": "demo"
}

2. Query the track event with ?$orderby.

GET {{urlProfileTrackeventsAPI}}/?$orderby=EventTime desc

Expected:
All track events are returned with the correct order.

Actual:
Returns 500 Internal Server Error.

P/S: no such issue when GET track event with $skip/$top
