Spread of any object into jsx causes react/prop-types to stop working (errors not detected)

Here is a minimal example:

```
import React from 'react'

class MyComponent extends React.Component {
	render() {
		// should be "'someProp' is missing in props validation (react/prop-types)" but is not
		this.props.someProp()

		return <div {...{}} />
	}
}

export default MyComponent
```

remove the spread ```{...{}}``` and everything is fine
