route() returns incorrect URLs when request is not handled by index.php

What did you expect to happen?

I expected route() to return correct URLs whenever used.

What actually happens?

When used outside of the frontend or console route() prefixes the URLs with whatever .php file WordPress handled the request via.

So http://localhost/my-route becomes http://localhost/wp/wp-admin/admin-post.php/my-route etc.

The issue can be solved by calling Illuminate\Support\Facades\URL::forceRootUrl(home_url()) during boot but I am not sure about possible caveats.

Steps to reproduce

1. Add Route::get('/test')->name('test'); to routes/web.php
2. Add add_action('admin_post_nopriv_route_test', function() { echo route('test'); }); to functions.php
3. Open /wp-admin/admin-post.php?action=route_test as appropriate for your local environment
