* Load Maps on Round Start, not Round Restart
* Fix admin log test.
It assumed maps/grids existed during pre-round, wihch is not a valid assumption anymore after this PR.
* Shutdown server if round fails to start 5 times.
* Fix bugs with round starting flag.
* Make StartRound not async, synchronously get new round ID from DB.
* Handle StationId.Invalid in PickBestAvailableJob
Instead of crashing, return null.
SpawnPlayer will handle this by making the player an observer or returning them to the lobby.
