UHF-12607: Fix GhostCard and url-parameter type error issues on job search

[teroelonen]

UHF-12607

What was done

• Changed the GhostCards to be displayed in a similar way as in School search.
• Fix issues with url parameters being interpret incorrectly for example when refreshing the job search page with some filters applied.
• Don't show the pager when there is results for only one page.

How to install

• Make sure your instance is up and running on latest dev-branch
  • git checkout dev && git pull origin dev
  • make fresh
• Update the HDBT theme
  • composer require drupal/hdbt:dev-UHF-12607
• Run code updates
  • make drush-locale-update drush-cr

How to test

•  Go to https://helfi-rekry.docker.so/fi/avoimet-tyopaikat and add some filters for the front page block. Submit and make sure the results are shown correctly.
• Add some network throttling and change the filters on the search. Make sure that multiple ghost cards are shown and that the previous results don't linger but are replaced with the ghost cards instead while loading. You can check what the broken layout looked like from the ticket.
• Now you need to test the filters carefully: Change all the filters, submit the search AND then refresh the page after seeing the results. The refresh should show the same results and console shouldn't have any errors. Test all kinds of combinations.
• For the final check, select filters that yields less than 15 results. Make sure the pager is not visible. No point in showing the pager in the case where it cannot be used.
• Check that the code follows our standards.
• Check that the differences in visual regression tests are appropriate.
