No subscriptions are fired for CREATED when querying previousValues

[marktani]

Current behavior

Subscribing to previousValues in a CREATED subscription prevents subscription events from firing.

Reproduction

For this mutation:

mutation {
  createItem(title: "Test") {
    id
  }
}

this subscription works as expected:

subscription {
  Item(filter: {mutation_in: [CREATED, UPDATED]}) {
    mutation
  }
}

This one doesn't:

subscription {
  Item(filter: {mutation_in: [CREATED, UPDATED]}) {
    mutation
    previousValues {
      id
    }
  }
}

Expected behavior?

The event is fired, and previousValues is null.
