`chalk load --help` produces an error, unlike `chalk help load`

## Description

`chalk help load` works as expected:

```console
$ chalk help load
load command
Load a new configuration into the chalk binary

...
```

However, `chalk load --help` produces an error:

```console
$ chalk load --help
error: chalk: When parsing command 'load': Too few arguments (expected 1)
```

`chalk help ` and `chalk --help` currently do the same thing for every command except:

- `load` (this issue)
- `help`: https://github.com/crashappsec/chalk/issues/168
- `docgen`: https://github.com/crashappsec/chalk/issues/170

I'd suggest that they always do the same thing.

## Impact

A user who runs `chalk load --help` doesn't get help for `load`.

## Steps to Reproduce

Run `chalk load --help` with chalk 0.3.1.

Start by reproducing `chalk help load` and `chalk load --help` with Chalk 0.3.1, then trace the CLI command-parsing and help-handling entry points for `load`. Compare the behavior with another command where both forms work. Done means `chalk load --help` displays the `load` help instead of reporting that an argument is missing.
