refactor(core-blockchain): initialize blockchain when resolved first time

[rainydio]

Summary

Blockchain class was resolved during register, which chain-resolved wallet repository and all wallet indices which were registered, any wallet index that is registered afterwards wasn't available.

The reason why it was resolved is because Blockchain class needed additional constructor logic to setup state machine. I marked initialize function with @postConstruct decorator and removed direct resolve and initialize call from register.

Now plugin that adds wallet index (e.g. core-magistrate-transactions) doesn't have to be registered before core-blockchain.

I tried to reuse core-api integration test setup for core-magistrate-api by exposing ...plugins argument in core-api test setup function. Apparently not only core-blockchain, but also core-forger and core-api prevent me from doing that. Not gonna pursue that any further.

This in itself is worth merging anyway.
