remove useless queries with false conditions (e.g 1=0)

What does this MR do?

Remove useless queries with false conditions (e.g 1=0).

The additional query with false condition is generated from IssuableCollections#issuable_meta_data when issuable_ids is empty:

(e.g. SELECT "merge_requests_closing_issues"."issue_id", COUNT(*) as count FROM "merge_requests_closing_issues" WHERE 1=0 GROUP BY "merge_requests_closing_issues"."issue_id" )

To reproduce it locally, visit this url: http://localhost:3000/gitlab-org/gitlab-test/issues?scope=all&utf8=%E2%9C%93&state=opened&search=test.

Are there points in the code the reviewer needs to double check?
