[GAMEPLAY] Initial ward timing resets fully if you sell/undo/buy anything else

When you start a game and buy a trinket, you have 1 charge. If you buy a different ward that you won't have any charges with a 120 cooldown. If you go to undo your purchase you still have 0 charges with 120 second cooldown. So any mistake of buying a second trinket to replace your first, or simply undoing too many purchases will reset your initial trinket.
