Deprecate GetFromListMixin

This mixin provides a workaround for get() for GitLab objects that don't
implement a 'get a single object' API. We are now getting conflicts
because GitLab adds GET methods, and this is against the "Implement only
what exists in the API" strategy.

Also use the proper GET API call for objects that support it.
