When the project has invitees, no group members were
returned due to a `user_id NOT IN (42, NULL)` query which
always returned [] since a `user_id` would be NULL, thus the condition
could never match.

Fix css lint

I merged [CE->EE](https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/953) with [failing css lint](https://gitlab.com/gitlab-org/gitlab-ee/builds/7216539), this is a fix.
It was caused by https://gitlab.com/gitlab-org/gitlab-ee/commit/d6d22a5dbd2ee04b59b2a80b3b6228575c3ea3ec on CE side.

@iamphill Please take a look if fixes are OK. If no, please send a separate MR to fix it.

Remove wrong '.builds-feature' class from the MR settings fieldset

EE MR for gitlab-org/gitlab-ce!7930

See merge request !947

Fix milestone total weight is missing on the milestone page

Fixes #1340

See merge request !944

- Move `ProctedBranchAccessEe` to `EE::ProtectedBranchAccess`. This is a lot
  cleaner, and has a precedent (`EE::Group`).

- Include `EE::ProtectedBranchAccess` inside `ProtectedBranchAccess`, instead of
  including both in the model classes. `EE::ProtectedBranchAccess` depends on
  `ProtectedBranchAccess` - this is a good way to model that dependency.

- Remove author credit from CHANGELOG entry

Allow public access to some Tag API endpoints

Continuation of #4269.

Fix typos in API doc examples

Fixes a typo in the API docs. The `curl` examples in [build_triggers.md](doc/api/build_triggers.md) and [build_variables.md](doc/api/build_variables.md) all have a typo in the auth header. They all say `PRIVATE_TOKEN` when it should be `PRIVATE-TOKEN`.
