Issue 205: Resolved issue with emoji in page titles.

[jamesmorrison]

Description of the Change

In some cases, the supplied post title is already HTML encoded, added a function to split emoji images to only show the emoji icon, not the HTML reported

Closes #205

How to test the Change

1. Install the plugin through git clone in the wp-content directory: git clone [email protected]:10up/simple-page-ordering.git
2. Checkout the issue/205-dragging-page-with-emoji-renders-html-in-page-title branch
3. Install dependencies: composer install; npm install; npm run build;
4. In test install, activate plugin
5. Create and publish a page with a title that contains emoji, e.g. "hey there! 👋"
6. Reorder the menu item with the emoji
7. Confirm the emoji remains as an emoji; you do not see HTML content
