The imprint template from the content repository broke after the update to Twig 3.0 in the content provider repository. We can trace down the error to the lines

        {% filter nl2br %}
		{%- include 'address_of_suborganization.twig' %}
        {% endfilter %}

in the imprint.twig template. If we remove the filter statement, the template works. This ticket is about finding out what has changed and fixing it.

Acceptance Criteria:

• The content provider can filter rendered includes again
• The temporary quickfix that replaces the includes with their content is reverted.

Implementation Notes:
Ideally, the content provider repo itself reproduces the offensive template in a test and fixes it.
