Summary: Previously, `BaseTextShadowNode::getAttributedString` used to recurse on a list of `SharedShadowNode`s (i.e: the children). In the `RawText` base case of this recursion, we'll need to record the parent of the current `RawText` (so that we can dispatch the `onPress` event to it). Therefore, we need to start recursing using the `SharedShadowNode` itself, and not its children.
