Fix 7 wild dates flirty version

I read about this bug in the EA Bug Forum and it reminded me a lot of the Money Marriage bug. One look at the tuning file was enough to know that it was exactly the same bug. 
So I did the same as with Money Marriage and now you really have 24 hours for a perfect date. 

This version changes the last buff to Flirty because I found it more suitable for me. This should also be helpful for those whose Sims have the Carefree trait.
