fix consensus error

[noot]

Closes: #450

Description

• fix state transition to not use st.Csdb

instructions:

1. update Dockerfile to be the following:

FROM golang:1.14
RUN apt-get update && apt-get install -y \
  make curl jq tmux vim
COPY . $HOME/ethermint
WORKDIR $HOME/ethermint
RUN make install
ENTRYPOINT ["/bin/bash"]

2. docker build . -t emint

3. ethermintd testnet --v 3 -o ./testnet --keyring-backend=test --starting-ip-address=172.17.0.2 --chain-id 17

4. in 3 new terminals:

docker run -it --name node0 emint

docker run -it --name node1 emint

docker run -it --name node2 emint

5. in ethermint/ terminal: (can put in a script for efficiency)

cd ./testnet/
docker cp node0/ethermintd node0:/root/.ethermintd
docker cp node0/ethermintcli node0:/root/.ethermintcli
docker exec node0 mkdir /root/.ethermintd/config/gentxs
docker cp gentxs/node0.json node0:/root/.ethermintd/config/gentxs/gentx-node0.json
docker cp node1/ethermintd node1:/root/.ethermintd
docker cp node1/ethermintcli node1:/root/.ethermintcli
docker exec node1 mkdir /root/.ethermintd/config/gentxs
docker cp gentxs/node1.json node1:/root/.ethermintd/config/gentxs/gentx-node1.json
docker cp node2/ethermintd node2:/root/.ethermintd
docker cp node2/ethermintcli node2:/root/.ethermintcli
docker exec node2 mkdir /root/.ethermintd/config/gentxs
docker cp gentxs/node2.json node2:/root/.ethermintd/config/gentxs/gentx-node2.json

6. inside each node:

ethermintcli config keyring-backend test
ethermintd start --pruning=nothing > ethermintd.log &
ethermintcli rest-server --laddr "tcp://172.17.0.2:8545" --unlock-key node0 --chain-id 17 --trace > ethermintcli.log &

running the rpc server is optional for node1 and node2, if you do, change key to node1, or node2 respectively, and update the IP address to 172.17.0.3 or 172.17.0.4 respectively

7. inside node0:

curl -X POST --data '{"jsonrpc":"2.0","method":"eth_accounts","params":[],"id":1}' -H "Content-Type: application/json" 172.17.0.2:8545

use the resulting address as the from of the next step

curl -X POST --data '{"jsonrpc":"2.0","method":"eth_sendTransaction","params": [{"from": "0x8218156c38c4e1cd74ba2dbf9a9eb1c7adbc4f30", "to": "0xc4cc618d9d8bb05d21d9621cab9aeb984af92db7", "value": "0xA", "gasLimit": "0x5208", "gasPrice": "0xA"}],"id":1}' -H "Content-Type: application/json" 172.17.0.2:8545

8. for all nodes tail -f ethermintd.log and see tx get included w/ no consensus failures
