Set finalized_view to None when restoring in the Commit step

In the Tendermint restoring process, if the backup state is the Commit step, CodeChain set the step to the Precommit step and handles the votes. The purpose of the behavior is that calling functions that are called when enters the Commit state. After we introduce the `finalized_view_of_current_block` variable, the variable should be changed to `None` when CodeChain sets the state to Precommit in the restoring process.
