AutolinkExtension parses emails twice

[onigoetz]

Version(s) affected: 2.0.0

Description
Using CommonMarkCoreExtension and AutolinkExtension together with mail addresses results in nested links

How to reproduce

use League\CommonMark\MarkdownConverter;
use League\CommonMark\Environment\Environment;
use League\CommonMark\Extension\Autolink\AutolinkExtension;
use League\CommonMark\Extension\CommonMark\CommonMarkCoreExtension;

$environment = new Environment([]);
$environment->addExtension(new CommonMarkCoreExtension());
$environment->addExtension(new AutolinkExtension());

$converter = new MarkdownConverter($environment);

echo $converter->convertToHtml('[me@mydomain.com](mailto:me@mydomain.com)');

results in

<p>
  <a href="mailto:me@mydomain.com">
    <a href="mailto:me@mydomain.com">
      me@mydomain.com
    </a>
  </a>
</p>

But I would have expected (babelmark too) to get

<p>
  <a href="mailto:me@mydomain.com">
    me@mydomain.com
  </a>
</p>

P.S. Congrats and great work on V2 ! I'm integrating it in Daux and it's going well so far :)

Good find! It looks like this is essentially the same problem as #688, so a similar fix should work fine: #691 I'll have this merged and released sometime this week.

And thank you for the kind words!
