End previous background task as soon as begin task is called

Resolves: IOS-43

🎯 Goal

Make sure previous task is ended when begin task is called immediately.

🛠 Implementation

There have been cases where background tasks are not ended correctly. Although I haven't been able to reproduce this with the demo app, I did find one way to reproduce it. Involves calling begin task twice. Could it be that in some configurations this can happen, not sure.
