Merge branch '19102-fix' into 'master'

Fix an information disclosure when requesting access to a group containing private projects Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/19102. The commit speaks for itself: Fix an information disclosure when requesting access to a group containing private projects The issue was with the `User#groups` and `User#projects` associations which goes through the `User#group_members` and `User#project_members`. Initially I chose to use a secure approach by storing the requester's user ID in `Member#created_by_id` instead of `Member#user_id` because I was aware that there was a security risk since I didn't know the codebase well enough. Then during the review, we decided to change that and directly store the requester's user ID into `Member#user_id` (for the sake of simplifying the code I believe), meaning that every `group_members` / `project_members` association would include the requesters by default... My bad for not checking that all the `group_members` / `project_members` associations and the ones that go through them (e.g. `Group#users` and `Project#users`) were made safe with the `where(requested_at: nil)` / `where(members: { requested_at: nil })` scopes. Now they are all secure. See merge request !1973
