Remove sorting since it breaks rewrite rules.

Hi,

when using following hiera config:

```yaml
        location_custom_cfg:
            - rewrite ^/api/(.*) /index_rest.php/$1 last
            - rewrite ^/robots.txt /index_cnseo.php last
            - rewrite ^/sitemaps/sitemap.*.xml$ /index_cnseo.php last
            - rewrite ^/interstitial/.* /interstitial.php last
            - rewrite ^([^/]+/)?content/treemenu.*$ /index_treemenu.php$1 last
            - rewrite ^(.*)$ /index.php$1 last
```

it produces location code like:

```
        location /xy:
            rewrite ^(.*)$ /index.php$1 last;
            rewrite ^([^/]+/)?content/treemenu.*$ /index_treemenu.php$1 last;
            ...;
```

Due to sorting the index rule will be set on first position and therefore no other rewrite will ever match.
