Fixes vehicle noclip bug

Fixes the problem when a server has noclip disabled and a player removes the vehicle while getting out which causes the notorious vehicle noclipping bug.
Also fixes spelling error. :P

This is my first time using a pull request, hopefully I didn't mess it up.
(And it seems GM:CanExitVehicle actually runs even after the player has left the vehicle, does it have a certain expiration time? Don't know why nobody put something so simple in here to fix it.)
