[fix] dedicated named location per $app

[Gofannon]

fix multiple install on subdomains

Before this fix app1 => @dokuwiki - works app2 => @dokuwiki - fails

After \o/ app1 => @app1 - works app2 => @app2 - works

---

Problem

• Activating "URL rewriting" broke multiple install on subfolders
• All dokuwiki apps send their data to the same named location @dokuwiki
  • there can only be one functionnal instance per domain

Solution

• Create a dedicated named location per DokuWiki installation

Test

On the same domain (root or subdomain), install

1. https://myDomain/dokuwiki1
2. https://myDomain/dokuwiki2

Visit https://myDomain/dokuwiki2 and go to another page than $home (like $admin or create a $new page)

Conflict solved in CLI but I cannot push to master as an approval is required

To github.com:YunoHost-Apps/dokuwiki_ynh.git

Indeed, branches testing and master are protected, you can't commit directly to those branches.

As the app is not official anymore, you can merge in 3 days.
