fix: root is now rendered only once

[Grimones]

Before, there was only fix for dispatching APPLICATION_INIT once. However Root component was rendered twice. initAlready wasn't working as expected.

Proof.

This PR fixes this behaviour by updating the react-async-bootstrapper. react-async-bootstrapper has been updated to v2.1.0 which added an ability to expose bootstrapper context to components.

Now <Root /> renders only once.
