Timer to return to original position in list once stopped

Dependent on the implementation of #292 going forward and the implementation of #283

As a user with a previously prioritised list of timers,
I would like for a timer that has bubbled to the top of my list #292 to return to its original position when stopped
So that I don't lose the time and effort I have previously put into the prioritisation of my tasks.

## Acceptance criteria
+ [ ] When I press `Stop` to stop the timer, the timer stops and the list item returns to its original position/prioritisation order in my list
+ [ ] If my timer is stopped by the app for any purpose, the list item returns to its original position/prioritisation order in my list
