Transaction revocation is not considered

Bug Report

Description

When creating a new todo, the scenario that the transaction is revoked due to chain reorganization is not considered.
When the transaction is executed but then revoked, the todo item still shows on the UI which will make the subsequent transaction that aims to delete it fails, losing user's transaction fee.

Reproduce Steps

1. send transaction to create a new todo
2. When the transaction is executed, UI shows the new todo
3. Let blockchain reorganize by importing a side chain
4. The transaction is revoked and returns to transaction pool.
5. The todo item still shows in UI.
6. Now if we try to delete the item by click x, the transaction will always fail.

Expected Behaviour

If the transactions revoked by chain reorganization, the todo item in UI should be removed accordingly.

Hi @anony2020mous, thanks a lot for the effort you put in writing this issue ! Unfortunately as the latest commit shows, I completely lost track on this project and I currently am not willing to get back to it yet since I have moved on from the crypto world for some time now.

That said, if you want to contribute to this project and fix the problem, I really encourage you to submit a PR that I will gladly review and test 💪
