Parser fails if HTML content contains a <script> tag with a URL inside it

[dionc]

When testing OG we found that it failed to parse many websites that contain valid OpenGraph tags. We debugged it and found that the built-in Parser object fails to parse when it finds a script tag containing a web link, eg: <script>{"@context":"http://schema.org" … }</script>.

Here's an example URL that demonstrates the problem:

When OG encounters this issue it fails parsing entirely and doesn't return any meta data.
