including a form creates duplicate CSS-IDs

[fritzmg]

If you give a form a CSS-ID and include the form in the front end, the CSS-ID will be used for both the container element and the form itself.

Reproduction

1. Create a new form in the form generator and give it a CSS-ID, e.g. foo.
2. Include the form in any way in the front end:
   • Via an include content element.
   • Via <?= \Controller::getForm(…) ?>
   • Via {{insert_form::*}}.
3. Analyze the HTML output. It will be the following in all cases (either with ce_form or mod_form):

<div class="ce_form block" id="foo">
  <form action="foo.html" id="foo" method="post" enctype="application/x-www-form-urlencoded">
    …
  </form>
</div>
