Clean up search result classes

## What does this MR do?

Clean up search result classes

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

I checked if those methods are used and it seems like NO. But you can check as well.

## Why was this MR needed?

To be clean

See merge request !6216

This commit adds a job to the pipeline to test if migration on seed
data works. Even though the seed data is not perfect, it does give more
guarentees that this will succeed in the real world too.

seed_fu is used instead of dev:setup to save some time, as they both
generate the data in the same way, this should be fine.

Fix missing flash messages on service edit page

## What does this MR do?

This MR fixes missing post-update flash notifications for service edit page. Bug was introduced in https://gitlab.com/gitlab-org/gitlab-ce/commit/76aad9b76ed756ca9ba2cbcdb399c815e542b3ae#3ca7aff54d2814b971a98a7bf2837e07ab3dfa04_21_20 and caused by passing `notice: Successfully updated.` to path helper instead of passing it to `redirect_to` due to wrong parenthesis placement.

## Why was this MR needed?

While adding HipChat integration I noticed that no messages are being displayed after clicking on "Save changes" button. I looked into code and observed that there is a code for these messages which once worked but doesn't work anymore. It's a regression which should be fixed.

Safer ref updates

Use `git update-ref` to prevent clobbering concurrent ref updates. If
rugged/libgit2 is temporarily confused, due to concurrent `git gc` for
example, then it used to be possible to accidentally reset a ref to an
earlier state and lose commits. Because `git update-ref` does not get
confused by `git gc`, what will happen now is that the commit based on
confused information fails, preventing data loss.

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/20353
