add execute block call in follow-chain

[qiweiii]

closes: #70

An error I get is

 [11:05:18.948] ERROR (follow-chain/49419): Error when processing new head
    err: {
      "type": "Error",
      "message": "wasm `unreachable` instruction executed",
      "stack":
          Error: wasm `unreachable` instruction executed
              at Object.callback (/Users/qiweiyang/GitHub/chopsticks/packages/chopsticks/src/plugins/follow-chain/index.ts:134:23)
    }

Any clue how I should debug this? I can confirm the wasm I used is the one with try-runtime feature

it should log more information if you have LOG_LEVEL=trace.

[qiweiii]

seems the log is the same

[17:27:12.719] TRACE (executor/55366): taskResponse
    response: {
      "Error": "wasm `unreachable` instruction executed"
    }

what wasm are you using? looks like something wrong with wasm file

I am using wasm build from this

https://github.com/AcalaNetwork/Acala/blob/7198bb16bc6078cd574a2545aa0306161e2d196a/Makefile#L138

Remove true from setupContext

[ermalkaleci]

there's another problem as well. setupContext will start to latest and then we set head to finalized. So we need to set the correct block number in order to make wasm-override correct

[ermalkaleci]

this can't be implemented on follow-mode
