// NOTE: There is a fairly important semantic distinction here. It seems tempting to say that a failed vesting period should mean that 'GetVestedCoins' should not return those coins. While the point of a validator vesting account is to 'seize' or 'burn' unsuccessfully vested coins, they do in fact vest and become spendable. The intuition is that they have to be spendable in order for the bank keeper to allow us to send/burn them. If they were not vested, then a validator vesting account that failed all of it's vesting periods would never return/burn the coins because it would never have a spendable balance by which to do so. They way we prevent them from being spent in a way other than return/burn is by sending them in the BeginBlock and thus beating any other transfers that would otherwise occur.
