[BUGFIX] Avoid calling parse_url(null) in DatabaseRecordList

DatabaseRecordList::renderListRow() calls linkUrlMail() with
eventually null as second argument, thus invoking parse_url(null)
which emits a E_DEPRECATED PHP 8.1 error.

The patch sanitizes call in renderListRow(), adds type casts
in linkUrlMail() and a @todo to change signature in v12.
