No thread notification in TAC when just joining a room

### Steps to reproduce

- Join a room
- Post directly a thread message
- The other users don't see the notification in the TAC

### Outcome

#### What did you expect?
The other users to have notification

#### What happened instead?
They didn't get any notification. After some manipulations (ex: sending new messages, starting new threads) it is working again. They will see future notification.

We can see in the image below that we have a thread notification on the conversation, that didn't show on the TAC

I saw in the console some errors but not sure if it is related :
`Error sending receipt
Object { room: "!zefzrfzrf:matrix.org", error: M_FORBIDDEN }
error: M_FORBIDDEN: MatrixError: [403] You don't have permission to access that event`

And also this one on the receiving side :
`Got room state event for unknown room !fezfez:matrix.org!`
