fix(core): Prevent text duplication from props.children and HostText child fibers

In real React Native fiber trees, <Text>Hello</Text> has both
memoizedProps.children = 'Hello' on the Text fiber and a child HostText
fiber with memoizedProps = 'Hello'. Skip child recursion when
props.children is a string to avoid collecting the same text twice.
