Multi-Stage Node Handler Registration

[SIMULATAN]

The current system is prone to race conditions. If the first Node Handler in the chain wants to use the Json dependency, it'll be created prematurely and lack the other Node Handler SerializersModules.

Instead, split the registration process into multiple stages. First, load all Koin modules. Only when all modules were loaded, create and register the NodeHandler. This should avoid these issues in the future?

Once that's done, check through the existing code to spot : Json = by inject() usages and try to replace them with eager injection. With this new system, this should also work just fine.
