prevent `tryRunPluginHelp()` execution on non-1st-level commands. 

commands comes in the form of `rootCmd 1stCmd 2ndCmd` and the `tryRunPluginHelp()` function takes the command name to run plugin help in the form `docker-<command name>`, if command name matches a plugin name it will display the wrong help message.

to make sure we're using 1stCmd level we check if the root command is the same as the command parent.

e.g. `docker swarm init --help`
```
docker: is the root command
swarm : 1st level command
init  : 2nd level command
--help: is a flag
```

this approach is not taking in consideration if a plugin and 1st level command matches, for example `docker foo` command and `docker-foo` plugin.
