MiniCart::process_template_contents │ protected │ WC 1.0

Process template contents to remove unwanted div wrappers.

The old Mini Cart template had extra divs nested within the block tags that are no longer necessary since we don't render the Mini Cart with React anymore. To maintain compatibility with user saved templates that have these wrapper divs, we must remove them.
