On Project settings page the "CI Events" link navigates to wrong/old ci page
I found this problem in 8.1.2-CE.
When you clicked to "Ci Events" link in the project settings section in sidebar, you are redirected to an old style (pre 8.1) ci page without other links on sidebar.
For example:
You are on the: https://<gitlab url>/<group name>/<project name>/ci_settings/edit
page and want to view the ci events and you clicked on "CI events" you are redirected to https://<gitlab url>/ci/projects/1/events
page and your sidebar are contains olny the CI Events link.
