[Bug] Notification always shows "Initializing"

### Checklist

- [x] I made sure that the issue I am raising doesn't already exist

### Current behaviour

These are the unexpected behaviours:

- The notification always shows "Initializing".
- There is no way to remove it.
- Even when the timer has finished, it is still there, "initializing"

### Expected behaviour

I would like:

1. The notification shows the current task
2. When the task is over I can close it - or always swipe it away.
3. Already there: When I click it, I get to the app
4. The notification updates and shows the secods/minutes remaining

### Steps to reproduce

1. Create a timer with 30 seconds work, 10 seconds rest, and 3 active intervals...
2. Start the timer
3. swipe down to see notifications
4. Swipe the notification to the side - it stays
5. Wait until the timer is done
6. Notification is still there, cannot be swipes, still says "Initializing"

### Additions

The timer shows 11:45 - I do not know if this is the time it was created or the minues/seconds it stopped working. It runs for 15+ minutes and also, I have a 1 second "break" part in there.
