Redundant check condition

[ThanhNhann]

I see that MustRefundWager function checks three conditions with MoveCount but when we use it at EndBlocker, it just checks the case MoveCount == 1 and then calls MustRefundWager here, so it will always point in one case in MustRefundWager function and will never go to another cases like MoveCount == 0

Yes. MustRefundWager exists and should cover all situations, regardless of how it is being used.

The fix I see is that EndBlocker does not need to make the extra check for == 1 because == 0 is a valid situation.

I will include that in a future revision of the code.
