Epic #85006: Reduce falsely reported broken links
Remove (or do not show) stale broken links in tx_linkvalidator_link
If a page (or content element, or ...) is removed, the related broken links are not removed from tx_linkvalidator_link.
They are not displayed because only broken links of subpages of current page are displayed, so it is not a huge problem. But, eventually, this clutters up the tx_linkvalidator_link table.
Currently, there is no possibility to remove stale (no longer relevant) broken links except removing them manually from the db table.
