Jake Craige 9db36f7ba3 Improve serve command error message (#2017)
Update the command matcher for the server command to log a more helpful
message when it's called without a subcommand.

Before:
```sh
$ target/debug/grin server
:: Some(ArgMatches { args: {}, subcommand: None, usage: Some("USAGE:\n    grin server [OPTIONS] [SUBCOMMAND]") })
```

After:
```sh
$ target/debug/grin server
Subcommand required, use 'grin help server' for details
```
