Intialization
This sub-project is about initializing the default data so the server is ready to start. Currently, it also creates 10 accounts for testing.
The state of this sub-project is probably pretty messy and very incomplete, so please don't wonder.
The initialization code is called by the a migration of entity framework core. However, it's independent from it, so if we ever want to switch it's reuseable.
It's tested by an integration test in the corresponding Test-project. The test runs the initialization on a real database instance and tries to load the game configuration and one of the created accounts.
