Fix channel ordering glitch

[VelikovPetar]

🎯 Goal

We are wrongly considering thread replies for calculating the last channel message (when channel is read from DB, before it is loaded from BE). This PR excludes thread replies from the last channel message calculation.

🛠 Implementation details

• Exclude thread replies from the last channel message calculation.

🎨 UI Changes

Before	After
before.mp4	after.mp4

🧪 Testing

1. Enter a channel (not the one on the top, it should be a channel lower in the list)
2. Write a message
3. Then write a thread reply
4. Kill the app
5. Open the app again
6. There should be no re-ordering of the channels
