[BUGFIX] Apply previous site identifier as fallback for URL resolving

Prior to #93240 URL routes were reverse sorted using the corresponding
site identifier (which did not contain any URL information). For the
scenario of matching undefined URLs (e.g. base URL is "/website/", but
request was like "https://example.org/"), the first item of a reverse
sorted list was used.
