Sitemap uses `generate()` results, which were using `_rec_name` as slugified
URL.
Routing map has endurl using slugified `display_name` which is checked against
during `dispatch()`, that will redirect 301 to that url.
For instance:
- `/shop/product/acoustic-bloc-screens-23` is listed in sitemap while this
URL is not the correct endpoint. Reaching this URL will 301 redirect you to
`/shop/product/furn-6666-acoustic-bloc-screens-23`.
- `http://localhost:8069/event/design-fair-los-angeles-1` in sitemap which
redirect to `/event/design-fair-los-angeles-2020-02-14-2020-02-18-1`.
Sitemap should contains endurl, not 301 URL.
