r2085: assertion fails after removing a station

[Bernd Gabriel]

assertion at line 1173 in vehicle/simvehikel.cc fails.

Steps to reproduce:
1) build 3 stations
2) connect them with a convoy
3) at 1st station convoy loads freight for 2nd station
4) remove 2nd station before convoy arrives
5) when convoy arrives at 3rd station, assertion fails, because ware.gib_zwischenziel().is_bound().

Attached savegame (pak64) is saved between steps 3 and 4.

Aparently I just started debugg after posting. This is rather by coincidence, since I usually do not have time to program after 20-21h in the evening ...
