Strange urls: nested entries include {mount} several times

[alexveklenko]

Bug description

Problem:
{parent_uri} appends {mount} at every point in URI hierarchy, so with depth > 1 it starts to add up, e.g.:
given permalink structure /{mount}/{parent_uri}/{slug} it behaves like this:
1st level - /top/lvl1 (parent_uri = '')
2nd level - /top/top/lvl1/lvl2 (parent_uri = '/top/lvl1')
3rd level - /top/top/top/lvl1/lvl2/lvl3 (parent_uri = '/top/top/lvl1/lvl2')

How to reproduce

Orderable collection's route structure is '/{mount}/{parent_uri}/{slug}'
Create nested entries and check uri

Possible solution: src/Routing/UrlBuilder.php

public function build($route)
    {
        // Routes can be defined as a string for just the route URL,
        // or they can be an array with a route for each locale.
        $route = (is_array($route)) ? $route[$this->content->locale()] : $route;

        $route = $this->convertToAntlers($route);

        // keep {mount} only for the top level entries
        $routeData = $this->routeData();
        if (isset($routeData['depth']) && $routeData['depth'] > 1) {
            $routeData['mount'] = '/';
        }

        $url = Antlers::parse($route, $routeData);

        // Slugify it because we're dealing with URLs after all.
        $url = $this->slugify($url);

        // If provided variables had no matching value, we would end up with
        // blank spaces in the URL, possibly resulting in double slashes.
        // Tidying up the URL will de-duplicate those extra slashes.
        $url = URL::tidy($url);

        $url = rtrim($url, '/');

        return Str::ensureLeft($url, '/');
    }

Only include {mount} at the top level.

route: '{{ depth == 1 ?= mount }}/{{ parent_uri }}/{{ slug }}'

or

route: '{{ if depth == 1 }}{{ mount }}/{{ /if }}{{ parent_uri }}/{{ slug }}'
