Performance tests EventBus issue

[dmitry-ganzha]

ToDoListPT class contains disabled test, which do following actions:

• Create several tasks concurrently
• Retrieve projection which should contain all created tasks.

Expected Result

The Projection should contain as many tasks as we created.

Actual Result

The Projection contains unpredictable number of tasks.

Issue Summary
If create several number of tasks concurrently, produced events should appear in EventBus, because of concurrently invocation, events are overwriting each other as we don't see all events.

Possible Solution
Create new layer in Spine before EventBus, which will collect and feed EventBus with events when needed.
