fix: members: use new *All objects for *AllManager managersjlvillal/all_objects

Change it so that:

  GroupMemberAllManager uses GroupMemberAll object
  ProjectMemberAllManager uses ProjectMemberAll object

Create GroupMemberAll and ProjectMemberAll objects that do not support
any Mixin type methods. Previously we were using GroupMember and
ProjectMember which support the `save()` and `delete()` methods but
those methods will not work with objects retrieved using the
`/members/all/` API calls.

`list()` API calls: [1]
  GET /groups/:id/members/all
  GET /projects/:id/members/all

`get()` API calls: [2]
  GET /groups/:id/members/all/:user_id
  GET /projects/:id/members/all/:user_id

Closes: #1825
