Stop season popup flashing when purchasing buildings/upgrades

Disabled the Game.seasonPopup.reset() while simulating buy.
The Clicker code added the reset() to the buyfunction(). Every time CM
simulated a buy, the reset was called, which caused CM screen flash logic
to execute.
Changed variable name to matched renamed Cookie Clicker variable 'storeToRefresh'
