Queries with array parameters are failing

[nbigaouette]

The API for listing merge requests, filtering with multiple iids says that multiple iid can be used to filter the output.

For example, the following should be working:
GET /projects/:id/merge_requests?iid[]=42&iid[]=43

Unfortunately it does not work. This does not seems to be a problem with this crate but from GitLab itself. Maybe the docs are wrong?

 -> curl "http://gitlab.com/api/v3/projects/123/merge_requests?iid[]=1&iid[]=2"
{"error":"iid is invalid"}
