## Description
Closes: #10450
* `cosmovisor help` should not print any error.
* `cosmovisor version` should print more clear message if it can't run `app version`.
## Before
```
~/tmp ❯ cosmovisor version
Cosmosvisor - A process manager for Cosmos SDK application binaries.
Cosmovisor is a wrapper for a Cosmos SDK based App (set using the required DAEMON_NAME env variable).
It starts the App by passing all provided arguments and monitors the DAEMON_HOME/data/upgrade-info.json
file to perform an update. The upgrade-info.json file is created by the App x/upgrade module
when the blockchain height reaches an approved upgrade proposal. The file includes data from
the proposal. Cosmovisor interprets that data to perform an update: switch a current binary
and restart the App.
Configuration of Cosmovisor is done through environment variables, which are
documented in: https://github.com/cosmos/cosmos-sdk/tree/master/cosmovisor/README.md
