show only groups an admin is a member of in dashboards/grops

See merge request gitlab-org/gitlab-ce!17884

Gitaly-Ruby is not a Rails application, which made the method not exist
after the vendor. This patch uses direct indexing, which has the same
properties that `#first` has.

Remove legacy storage path call

See merge request gitlab-org/gitlab-ce!18598

authentication, that needs to be done in some, but not all doorkeeper controllers.
