Possible false positive in the config validation

[okonet]

Following config

  "lint-staged": {
    "linters": {
      "*.js": [
        "npm run lint:js -- --fix",
        "git add"
      ],
      "*.json": [
        "npm run lint:js -- --fix",
        "git add"
      ],
      "*.md": [
        "npm run lint:md -- -o",
        "git add"
      ]
    },
    "verbose": true,
    "concurrent": false
  },

causes the following error when running lint-staged:

Running lint-staged with the following config:
{
	linters: {
		'*.js': [
			'npm run lint:js -- --fix',
			'git add'
		],

}

Could not parse lint-staged config.
Make sure you have created it. See https://github.com/okonet/lint-staged#readme.

Error: Invalid config provided to runAll! Use getConfig instead.


husky > pre-commit hook failed (add --no-verify to bypass)

Then config is changed to following error disappears:

  "lint-staged": {
    "linters": {
      "*.js": [
        "npm run lint:js -- --fix",
        "git add"
      ],
      "*.json": [
        "npm run lint:js -- --fix",
        "git add"
      ],
      "*.md": [
        "npm run lint:md -- -o",
        "git add"
      ]
    },
    "verbose": true
  },

I've identified the problem and it's the sketchy comparison for null/undefined here:

https://github.com/okonet/lint-staged/blob/d99eb3815cbcb7f76d0adf693fe4017c8e31cf7c/src/runAll.js#L17

I'll create a fix soon.
