"Fix behavior of ldap_person method in Gitlab::OAuth::User" for 7.12

See !837

Fix behavior of ldap_person method in Gitlab::OAuth::User

Code tweaks in 45e9150a caused the ldap_person method to not return expected results.
Improved tests to cover the ldap_person method, which was previously stubbed.

Restored the previous implementation of ldap_person, as I could not find a more concise to write it that still works with all the test cases.

This controller is now the target for `root_url`. It sub-classes
DashboardController so we can render the old default without a redirect
if the user hasn't customized their dashboard location.

Kerberos require to stable 7.12

!819 to 7-12-stable

If kerberos is enabled require it

Since 'group: :kerberos' got [included in the Gemfile ](https://gitlab.com/gitlab-org/gitlab-ce/commit/2391a43a7073b4e723e9ca1f7ff19b30f8e51452) Kerberos no longer got [loaded when the app started](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/config/application.rb#L6)

This caused `Devise::OmniAuth::StrategyNotFound` error once Kerberos is enabled, failing to start GitLab .

With this we hopefully do not need to remove group from the Gemfile.
