Fix missing Git clone button when protocol restriction setting enabled

If Git clones are restricted to either HTTP or SSH-only in the
application settings, the clone button would not show. The refactoring
in https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/22196 broke
this.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/55676
