Function headless_lms_models::peer_review_queue_entries::upsert_peer_review_priority

pub async fn upsert_peer_review_priority(
    conn: &mut PgConnection,
    user_id: Uuid,
    exercise_id: Uuid,
    course_instance_id: Uuid,
    peer_review_priority: i32,
    receiving_peer_reviews_exercise_slide_submission_id: Uuid,
    received_enough_peer_reviews: bool
) -> ModelResult<PeerReviewQueueEntry>

Inserts or updates the queue entry indexed by user_id, exercise_id and course_instance_id.

The value for receiving_peer_reviews_exercise_slide_submission_id never changes after the initial insertion. This is to make sure that all received peer reviews are made for the same exercise slide submission. The same applies to received_enough_peer_reviews to avoid the scenario where it might be set from true back to false.
