Merge branch 'fix-missing-flash-messages' into 'master'

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.
