Double receiving notifications when using the desktop application

### Steps to reproduce

1. install element desktop, log in and launch it.
2. Install element android, log in and put the phone in standby mode.
3. start a chat with someone via element desktop.

### Outcome

#### What did you expect?
No notification on my phone because I have Element Desktop open and thus marked as online.

#### What happened instead?
My phone makes a notification for *any* message, which is very annoying.
