[BUG_SP] Unload sugar beet auger wagons in the field

[Findus97]

Steps to reproduce
Use the Bergmann RRW 500 (or the Holmer Terra Variant with MB35) to unload a sugar beet harvester and unload in the field.

Actual behavior
The trailer works fine for one round. After unloading the second time, the tractor with the RRW 500 isn't moving to the harvester.

Expected behavior
Find a path to the harvester and unload it after the second round.

Yeah that need a general enhancement.
Can't tell you when we get to this.

Should work better now, but its not perfect yet.
Hard to find a good solution for this, but we keep an eye on it.
