Fix "flip vehicle" not working

[NylanderrDK]

Describe Pull request We received a bug report that the "flip vehicle" option weren't working, and I looked into it. It wasn't working with the previous function for getting the vehicle, and I replaced it to get the vehicle the ped is in - and now it's working. So it's basically fixing a function not working.

The flip vehicle option works fine. You must be stood outside the vehicle, stood close to it and facing it. Then it works. If you are not looking at it, the raycast won't find the vehicle.
