applyStyle doesn't check null or undefined cases

[fluiddot]

I spotted that if you have a render rule that potentially returns null or undefined and you use applyStyle in other rule it could produce an exception.

Here is my case:
I don't want to render anything when I have softbreak in the markdown but for textgroup items, depending on the children I have to render a View or a Text. Besides when I have to render a View in a textgroup item I need to use applyStyle for styling possible texts inside.

In this case when applyStyle is called it tries to get type of the null child and crashes.

react-native-markdown-renderer/src/lib/util/applyStyle.js

Lines 16 to 18 in 260fad0

	if (child.type.displayName === type) {
	return <Text key={child.key} {...child.props} style={[].concat(child.props.style, styles)} />;
	}

Hey, i removed applyStyles here iamacup#32 in the react-native-markdown-display fork.

This was possible because of the change here: iamacup@e0b726c

Thanks @iamacup, I’ll take a look to your fork (nice work btw).
