Pokeshell Attacks Cause Delayed Fleeing

When dupes are running past aggressive Pokeshells (dropping off polluted dirt and then leaving, for instance), if the Pokeshell starts to make an attack as the Duplicant is already leaving, the attack won't do any damage immediately.

Instead, when the Duplicant arrives at their next task and begins working (even if that's quite a few seconds later), they will flinch, take damage, and pop up the "fleeing" alert when beginning the new task, even though they're no longer remotely close to the Pokeshells.

Doesn't cause any significant gameplay issues, but the "Fleeing!" message and damage when there is no obvious cause is very confusing at first.
