What is the current behavior?

The order of the lifecycle events is not backed by any test

What is the new behavior?

Added e2e test which checks which hook gets called in which order.

OnModuleInit -> OnApplicationBootstrap -> OnModuleClose -> OnApplicationShutdown.

If this is not the expected behavior, we would have to change the order.
