Frontend AI breaks when you execute an action for it manually.

This can sometimes happen when you play against AI. I originally only identified the "it sometimes breaks" problem and not the root cause. There already is a mitigation that will reload the page after 10 seconds of inactivity. Felix identified how this breaks and shared a way to reproduce it.

I think in my game it crashed. I think I picked up a union on Hedwigs turn. Before Hedwig was able to move.
It was an accidential double click.
Then it reset itself

This goes together with #126

It appears that this got fixed together with #126 by 402bbb8 at least I can no longer reproduce this problem. The reset code remains in place.
