renderPager() in DisplayPluginBase.php always return TRUE

I came across this ticket while trying to solve the issue described in https://www.drupal.org/project/search_api/issues/3274158 🐛 RuntimeException while trying to render item Active . I applied the patch.

Bad news: This patch did not resolve https://www.drupal.org/project/search_api/issues/3274158 🐛 RuntimeException while trying to render item Active for me.
Good news: This patch did not cause any problems that I noticed. So that's something.

Hi, For this issue, we can put a condition to check whether a pager is in use or not and then return TRUE to FALSE value accordingly. I have created a patch for this issue resolution. Thanks.

As a bug will need a test case showing the issue.

Thanks.

Re-rolled the patch. Please review.
