Subject: [PATCH] formatReactElementNode: convert displayName to String

If the `displayName` for a component turns out to be a `symbol` for some reason, ECMAScript will fail early when trying to implicitly convert it to a string. This explicitly converts to a string so that at least execution isn't halted.
