Cannot get commitlint to run when using lint-staged and cz-customizable

## Expected Behavior
When using `yarn commit` the expected result is to run `lint-staged` to lint all js and css files; then `git-cz` to generate a commit message; and finally `commitlint` to ensure that the scope and subject fields are formatted correctly.

## Current Behavior
Both `lint-staged` and `git-cz` run correctly and in the correct order, but `commitlint` is never triggered.

## Affected packages
* [x] cli
* [x] core
* [x] prompt
* [ ] config-angular

## Steps to Reproduce (for bugs)

1. Add `"commit": "lint-staged && git-cz --no-verify",` as a script in package.json.
2. In your `.lintstagedrc` file, add the following config:

```
{
"*.js": [
"pretty-quick --staged",
"eslint src/ --fix",
"git add",
"eslint --fix"
],
"*.css": [
"stylelint src/ --fix",
"git add"
]
}
```
3. In your `.huskyrc` file, add the following config:

```
{
"hooks": {
"pre-commit": "lint-staged",
"commit-msg": "commitlint -E HUSKY_GIT_PARAMS"
}
}
```
4. Finally, in your `.commitlintrc.js` file, add the following config items:

```
module.exports = {
extends: ['@commitlint/config-conventional'],
rules: {
'header-case': [2, 'always', 'lower-case'],
'scope-case': [2, 'always', 'lower-case'],
'subject-case': [2, 'always', 'lower-case'],
}
};
```

commitlint.config.js

```js
module.exports = {
extends: ['@commitlint/config-conventional'],
rules: {
'header-case': [2, 'always', 'lower-case'],
'scope-case': [2, 'always', 'lower-case'],
'subject-case': [2, 'always', 'lower-case'],
}
}
```

## Context
My absolute goal is to run `lint-staged`, then `git-cz`, then `commitlint` any time you run `yarn commit`.

## Your Environment
My project was started with `create-react-app` and has not been ejected. I’ve not even added any components yet — I’m just trying to get a solid, baseline codebase to start building on. Getting all of these tools to work well together has been tricky.
