Functional components returning conditionals fix

[jeremytowne]

• fixing an issue where the displayname was not being added to functional components that returned conditionals

Ex: If we have some functional component:

function MyComponent(props) {
  return props.someBoolean ? (<div>something</div>) : null
}

A displayName would not be added to this component without this fix.

+1 !! I also need this fix in my current project ! Glad to see it there, saves me some precious time if it's merged in. In the meanwhile, I have to add add "displayName" manually for conditional returns.
