What does this MR do?
When project has 3rd-party Issue tracker integration, clicking on
Issues tab will directly take user to issue tracker page. Starting %9.0 we changed navigation order for Projects (see #26348 (closed)), where we removed sub-nav items from
Merge Requests tab and showed them under
Issues tab. In this case, user will never see sub-nav since page is redirected to 3rd-party issue tracker.
This MR restores sub-nav under
Merge Requests when project has non-default Issue tracker (eg; JIRA, Bugzilla) integrated with the project. See #30779 (closed).
