Sometimes, HTML entities can be escaped twice, typically when getting sanitized …data from our `Onebox::OpenGraph` class then providing that value to a template. We’re using the Mustache gem to process the Onebox templates, and it will automatically escape HTML entities. This is usually not a problem, but it is for things like ampersands. For example, if the value we provide to the template is `&`, then Mustache will convert it to `&amp;`. This PR fixes that behavior by decoding the result of the sanitization we apply in `Onebox::OpenGraph`. That way, templates will get `&` instead of `&`, thus there won’t be any double escaping.
