Fix runtime panic below by bypassing the borrow checker.

You can easily reproduce it by implementing this:

    fn on_player_command_text(&mut self, player: Player, message: String) -> bool {
        if &message == "/spawn" {
            let vehicle = Vehicle::create(411, player.get_pos(), 0.0, -1, -1, -1, false).unwrap();
            player.send_client_message(
                Colour::from_rgba(0xFFFFFFFF),
                &format!("spawned vehicle with id {}", vehicle.get_id()),
            );
            return true;
        }
        if message.starts_with("/destroy ") {
            let id: i32 = message.split_whitespace().nth(1).unwrap().parse().unwrap();
            let vehicle = omp::vehicles::Vehicle::get_from_id(id).unwrap();
            player.send_client_message(
                Colour::from_rgba(0xFFFFFFFF),
                &format!("deleting vehicle with id {id}"),
            );
            vehicle.destroy();
            return true;
        }
        false
    }

Just make sure that the client actually streams in the vehicle before destroying it.
