Subject: [PATCH] Don't return empty string for `accessibilityLabel` for
 RCTView

Summary:
In case `RCTView` had no subviews, `RCTRecursiveAccessibilityLabel` was returning an empty string rather than nil.

I've noticed that https://fburl.com/i95iynxi returns empty string as well. Shall we change it there as well?
