Pushing vehicles while standing on vehicles bug

[Soyweiser]

When standing on a vehicle and using the grab function to push a different vehicle you get a debug warning message.

In order to reproduce:

1. Grab a shopping cart, wheelbarrow, whatever.
2. Find another vehicle and stand on it.
3. Try to push the grabbed cart/wheelbarrow while you're on another vehicle
4. Get debug message: map::board_vehicle:vehicle not found.

You do not need to grab the vehicle first and then move onto the second vehicle. Just pushing a vehicle from another gives the debug message.

Seems it is not related to the type of vehicle dragged.

Can replicate on 0.A, but not the most recent build -- suspect it's been fixed.

Can't replicate here.

All in all, it's just another squashed bug on the wall.
