[Bug] Persistent datatable filters causes incorrect redirects with multiple projects on subdomains

[madriegh]

Bug report

What I did

Install two project instances on subdomains, e.g. www.example.com/first and www.example.com/second
Create a CRUD panel with a list view and add filters.
Go to www.example.com/first/admin/your-crud. 
Select a filter. You will see that the 'admin_yourcrud_list_url' key is set in localStorage to enable the persistent filters.
Go to www.example.com/second/admin/your-crud

What I expected to happen

www.example.com/**second**/admin/your-crud opens

What happened

It will redirect back to the persisted url in the localStorage, which is www.example.com/first/admin/your-crud, the incorrect subdomain.

What I've already tried to fix it

I submitted a PR where I took the full url as key prefix for the localStorage instead of solely the route (#4843)

Is it a bug in the latest version of Backpack? Yes

After I run composer update backpack/crud the bug... is it still there? Yes

Backpack, Laravel, PHP, DB version
