Governance: Fix governance object syncing in AddOrUpdateVote. (#1061)

There is a bug AddOrUpdateVote function in CGovernanceManager. If a new vote has been arrived it is checked if a corresponding parent object are present in the mapObjects. If it is not we need to sync the parent object and return false. But the syncing is never performed because the corresponding code is placed after return statement. So we need to sync and then return.
