Add initial state to Bootrstrapper invocation

We need to decide what to do in `Bootstrapper` based in the initial state quite often. Right now this needs to be passed manually to implementation constructor, which is quite inconvenient when e.g deciding the initial state based on `TimeCapsule`, as a reference cannot be stored for it inside constructor.

Proposed solution is to change `Bootstrapper` and `BaseFeature` so that initial state is passed automatically to invocation.

Start by reading the Bootstrapper and BaseFeature invocation paths, especially how initial state is currently passed to implementation constructors. Trace the TimeCapsule-related use case described in the issue. Done means initial state is passed automatically to invocation without manual constructor handling, with the affected behavior covered by the repository's existing tests.
