fix(#643): Wrong items shown when reopening todo list
requested to merge 643-when-reopening-a-todo-list-on-app-start-wrong-items-are-shown into development
We fixed a bug which could cause the wrong items to be shown when e.g. reopening the app and - in this scope - a previously open todo list (or other type of container item) was reopened.
The issue was caused due to a race condition, which is now fixed.
Closes #643 (closed)
