Wrong link "Edit this page" when using Multisite

[ftertre]

When we are using the multisite setup of Grav, especially the one with subdirectories, the link to the Git resource for editing the page is wrong.

We expect to have:
http://mygit/myproject/blob/master/pages/01.basic/01.sometopic//docs.md
But we have instead:
http://mygit/myproject/blob/master/sites/mysite/pages/01.basic/01.sometopic//docs.md

Where http://mygit/myproject/ is the root of the git project (on github, gitlab of any other system), the page is /basic/sometopic and the site in multisite setup is in the mysite directory. It means the doc is accessible via http://mydoc/mysite/basic/sometopic.

The sites/mysite is in the way. Learn2 just imagine that the root folder of the doc is directly in pages folder when it is in pages/sites/mysite.
