I don't think this patch fixes anything broken.  If ferry's present
location needs a boat, the ferry will stay there.  The only case when it
will go for another city is if this other city is about to finish its
build (and thus has a higher priority).

If this behaviour is unwanted, it can be fixed by removing some of the
checks in the body of the function.

I tend to think that yoyoying is a consequence of the city production
yoyoing.  However, if the yoyoing has a constant period, there might be
deep bugs inside.
