Please give a concise description of the bug Regardless of the type of table view, if you select only one element and click on Download Selected or Delete Selected, we ge a HTTP 404.

What behavior did you expect? Redirect to single element download page

Which version does the issue occur in? Main branch

Optional notes and context Will wait until trust-stores branch is merged into main to fix it.

Suggested fix Add a redirect in both the TrustStoresMultipleDownloadView and CertificateMultipleDownloadView to TrustStoresDownloadView and CertificateDownloadView, respectively, if there is only one pk found.

Deletion was already fixed project-wide, but the issue was still present for downloads. I prepared a fix in #135
