UnitAI - FinishOrder called when order queue is empty

At turn 352 (r17033):

ERROR: FinishOrder called for entity 531 (units/brit_support_female_citizen) when order queue is empty

The error doesn't occur with r17027, but with r17028 and above. It is not an AI error but a problem with that commit (pathfinder).

Thanks for the quick emergency report ;)

(If you want to further debug it, you could try to reproduce it without AIs on a skirmish map with as few commands as possible. As you can see, the commands.txt file doesn't show the commands that the AI decides to order, so we need to try to replicate the problem otherwise. Probably not hard though.)

Fix edge case in the UnitAI state machine. Fixes #3429.
