// TODO
// 1. Test that a signed block by the ValidatorAddress increases the blocks counter, but not the missed blocks counter
// 2. Test that an unsigned block increass both the blocks counter and the missed blocks counter
// 3. Test that the previous block time gets updated at the end of each begin block
// 4. Test that the block before a pivital block doesn't reset the period
// 5. Test that a pivotal block results in coins being vested successfully if the treshold is met
// 6. Test that a pivotal block results in HandleVestingDebt
