Bug: node seed not acquired by node during setup

[iltoga]

Description

node seed is not acquired during node setup phase due to early initialization of nodeConfigurationService.
This leads to all nodes trying to register their address by using an incorrect public key (the one from nodeSeed = "") and failing to do so (because there is no such public key in node registry and only registered nodes can add their addresses to db).

Steps to reproduce

1. run a registered node
2. verify that node address is not in node_address_info table

Expected behavior

every registered node must have an address in node_address_info table.
