Add test case for not allow author to approve

This is more direct in loggin who approved a rule.

Utilze the new group_users association

Keep snapshot of group member by persisting as explicit approver,
because group member can change after MR is merged.

Filter out inaccessible groups from MR author.

Code owner rules are queries on its own.

This is to enable MR override rule's `approvals_required` is never
less than the project rule's.

First the project rule is cloned if not overwritten in the MR.
The MR’s rule to approval mapping is then persisted.

These represents rules associated with MRs and projects.
Rules are further associated with User and Group as members.

ApprovalMergeRequestRule is associated with Approvals,
as a record of whom approved what when MR is merged.
This is because recomputation result can change in
the future when project approvers/group members changes.

This reverts commit 1d1e95c8

When run after ee/spec/features/dashboards/activity_spec.rb, this would
fail to find the correct constant with:

> NameError: uninitialized constant Events::RepositoryUpdatedEvent

I'm not sure why this was; we give `Object.const_get` a fully-qualified
constant, and it should look that up first before attempting the default
behaviour of finding constants in ancestor classes.

Alternatives:

- `Object.const_get("::#{current_namespace}...")` - didn't work.
- `"::#{current_namespace}...".constantize` - does work, but that is a
  bigger change as `#constantize` does much more work here.
