Prevent 500 error on search results if description contains relative link

Bug: If I add relative link to comment or description and search for it - I get 500 error on search page.

Reason for this is that we use `@repository` variable. But for pages like search it does not assigned.
In future we should avoid using such variables. Especially in markdown parser that can be used on different pages

Fix MR commenting system when new commits pushed

Fixes #1608

This conmmit fixes wierd behaviour when you see wrong comments about new
commits in merge requests.

Short explanation of a bug:
When you push new commits to project we updated `project.merge_requests`
with comment about push. But `project.merge_requests` includes also
merge requests from forks to origin project. So when you push to master
branch it commented on all merge requests from forks to origin where
source_branch was `master`
