manager: use validator set from state (#814)
This PR changes the signed header to use validator set from last state. Tests needed to be updated to use at least one validator (because `ValidateBasic` now fails if there's nil validators). Since they need to be able to handle multiple validators anyway, we're passing 2 validators for now. Fixes #812
