Fix validator unshuffling

[bobanm]

What was the problem?

This PR resolves #9040, resolves #9075 and resolves #9080

How was it solved?

• Fixed the bug in the engine where the original validator list array was sorted and then saved in sorted order to BFT Params Store
• Added config option [default to 0] to prevent validator shuffling before the configured block height, to ensure that the the new version can sync
• BONUS: Cleaned up and simplified BFT Method unit tests 😎

How was it tested?

• When running the app, validator's consecutive missed blocks now show correct value
• When running the app, the validators are shuffled after each round
• All tests are passing 👌🏻

Apart for comments from @shuse2, I have a couple of minor comments, unit test is failing coz probably you need to update schema snapshot
