🐛 Bug Report: Realtime not triggering document updates on parent for removals of association

### 👟 Reproduction steps ## Setup 1. Create two collections: `Assembly` & `Part` (or whatever you like) 2. Create a `two-way` parent-child relationship between the collections. Inside `Assembly`: i. **Attribute Key:** `parts` ii. **Attribute Key (related collection):** `assembly` iii. **Relation:** one-to-many iv. Ensure to set the "on delete" behaviour to "Set document id to NULL in all related documents" 3. Write some code using the web SDK to subscribe to the `documents` channel for the `Assembly` collection _only_ (`databases.*.collections.assembly.documents`) ## Testing 4. Use `createDocument` in the SDK to create an `Assembly` 5. Use `updateDocument` in the SDK on the `Assembly` created above to add a new `Part` document, which creates the association for you 6. Observe that the promise for the `Assembly` is called (as expected) when the association was created 7. **Observe in the Appwrite UI that the documents exist and have the data provided** 8. Now, use `deleteDocument` in the SDK on the `Part` above, to remove the part and the association from `Assembly` 9. Observe that the promise for the `Assembly` **is not called** 10. **Observe in the Appwrite UI that the `Part` no longer exists and the association in `Assembly` is gone** ### 👍 Expected behavior ✅ Real-time should send a payload update for `Assembly` when the association is **created** ✅ Real-time should send a payload update for `Assembly` when the association is **deleted** ### 👎 Actual Behavior ✅ Real-time should send a payload update for `Assembly` when the association is **created** ❌ Real-time should send a payload update for `Assembly` when the association is **deleted** ### 🎲 Appwrite version Version 1.4.x ### 💻 Operating system Linux ### 🧱 Your Environment Appwrite is self-hosted with docker-compose in a virual machine on Ubuntu 22.04. **Appwrite Version:** 1.4.1 **Appwrite SDK:** web ### 👀 Have you spent some time to check if this issue has been raised before? - [X] I c…
