This fixes gitlab-org/gitlab-ee#1520

- Use IssuesFinder for the /issues API resouce
- Tests for iid filter in project issues API resource
- Tests for No Milestone filter in issues API resources
  The "No Milestone" case was not previously tested, and the `/issues`
  resource did not support the the `milestone` parameter.
- Return issues where all labels match from the issues and project issues
  API resources, like the group issues resource already does. See
  https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/6825#note_17474533Signed-off-by: Rémy Coutable <remy@rymai.me>

Current filtering for "/projects/:id/issues" endpoint
returns no results for "No Milestone" query.

This PR introduces fix by copying filtering from "/groups/:id/issues"
which works as expected.
