Fix RaisePredictiveEvent prediction checks (#5294)

RaisePredictiveEvent was made to not check whether prediction is enabled in #3534. This doesn't make much sense to me and is causing various SS14 game logic to erroneously run when prediction is disabled.

Here's the fix PR. Also fixes the assert to actually work (checking Connected is wrong, it should've been InGame) and makes the new check also account for SinglePlayerGame.
