Fix events in case of `ConnectionService` restart

When `ConnectionService` was before killed and respawned it would cause
a new connection events for every online player, regardless of whether
they were generated before.

Now list of registered players is also saved in default variables for
`ConnectionService` and quick restart will not cause any issues.
