UHF-9786: Fix missing links

[Arkkimaagi]

UHF-9786

The links are not appearing without also defining extra information text.

For example this Kymp page has links in Finnish and Swedish, but only Finnish has extra information text and only that accordion is visible:

What was done

• The twig template if-statement was modified to check the actual content of the accordion, thus making the links visible even without the extra information text.

How to install

• Make sure your instance (KYMP) is up and running on latest dev branch.
  • git pull origin dev
  • make fresh
• Update the HDBT theme
  • composer require drupal/hdbt:dev-UHF-9786_missing_links
• Run make drush-cr

How to test

• Check that this local page has the links (and accordion) visible as in above screenshot.
• Check that code follows our standards
