Fix testing URLs with HTML entities

Previously testing a URL like this:

<a href="https://----.example.com?a=b&amp;c=d">This server does not exist</a>

Was a problem because the & was not properly understood.

This is a partial solution just for &, which is the most common HTML entity you will use. A complete solution will require adding a dependency or updating html-validate.
