extends does not work anymore

[markusguenther]

Hello,

I used

{
	"extends": ["xo-space/esnext", "xo-react/space"]
}

and it worked well until I upgraded eslint to version 4.x and the eslint-config-xo-react to the latest version. Since then I always get the the error that the config is invalid.

	Configuration for rule "react/require-default-props" is invalid:
	Value [{"forbidDefaultForRequired":true}] should NOT have more than 0 items.

I am using the following versions:

    "eslint-config-xo-react": "^0.15.0",
    "eslint-config-xo-space": "^0.17.0",
    "eslint-plugin-babel": "^4.1.2",
    "eslint-plugin-import": "^2.8.0",
    "eslint-plugin-jsx-a11y": "^6.0.3",
    "eslint-plugin-react": "^7.5.1",
    "eslint": "^4.15.0",

If I am removing "xo-react/space" in the extend array, everything is fine :(
Hopefully someone has a hint for me.
