Fix group search to check path as well as name

The API documentation says:

"You can search for groups by name or path with: /groups?search=Rails"

But you can't because the search query only checks the name, not the path. This fixes that.

See merge request !325

Fix the intermittently failing "Bar" search tests.

Over the past several months we've come to calling them the foobarred tests. We've seen them fail on our jenkins server, and on the GitLab semaphore tests.

In this merge request I scope the test checks for the foo barred tests to check within the .search-results div.

Fix for a "500: Encoding error" in the blame view

What does this MR do?

- The change enforces UTF-8 encoding on the source line data obtained from the Git.

Are there points in the code the reviewer needs to double check?

- The fix might not be enough to fix all encoding error issues in the blame view. There might be similar encoding issues if there are non-UTF-8 encoded names, for example

Why was this MR needed?

- This change fixes the "500: encoding error" that I get when I try to view the Gitlab source CHANGELOG file.

What are the relevant issue numbers / Feature requests?

- Gitlab issue #894: https://gitlab.com/gitlab-org/gitlab-ce/issues/894
