mediawiki: some links on a nonexistent page are invalid

[ya7on]

Description:
Some links in MediaWiki represent invalid links. Links on a nonexistent page are lead to localhost.

Selected links (search the related logs and create this page) are bad.

Steps to reproduce:

1. Go to your your hosted mediawiki;
2. Go to any nonexistent page. For example: https://DOMAIN.COM/w/PAGE_ADDR where DOMAIN.COM is your domain and PAGE_ADDR is your name of nonexistent page;
   
3. Click to search the related logs or create this page link;
4. Look at the current URL.

Expected result:
Links href should represent a valid url.

Actual result:
Links domain is 127.0.0.1:port instead of real valid domain on which the project is deployed.
