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

Fix randomly failing specs in expand_collapse_diff_spec:

This MR fixes the following random failure in a spec:

```

Capybara's `click_link` method doesn't actually wait for the page to reload.
When the `expand_all_diffs` parameter is used, we need to search for unique
elements that appear to ensure that the page has actually reloaded.

Fix markdown anchor icon interaction

## What does this MR do?
Fixes and improves the markdown anchor icon interaction so that hovering over any headers (generated through markdown) will have an anchor icon that's easily accessible (won't hide from you on edge cases), replaced the icon with fontAwesome icon and added more padding for the anchor icon.

## Are there points in the code the reviewer needs to double check?
1.  Need to check if it's okay to replace the icon-link.png with fontAwesome
2. Need to check if it's okay for the additional view padding on views that render markdown to compensate for anchor link space
3. Need to check if there are any other views that render markdown that did not have it's padding re-adjusted

## Why was this MR needed?
Improve markdown rendered anchor links so that they are more user friendly

## What are the relevant issue numbers?
Closes #20459

Fix expiration date picker after update

@DouweM this object is now on `gl`, not on the window. It would only break when trying to use the date picker on a newly-inserted member element, but I figure it's probably worth sneaking into a patch.
