Fix broken feature spec.
This older spec was failing: features/project/issues/issues.feature
Looks like before we were doing an exact match for queries, that's why it was passing with this existing issue: https://gitlab.com/gitlab-org/gitlab-ce/blob/59fa031e6f7d5a1b658c370f581c4caaf4493150/features/project/issues/issues.feature#L128
