Controller RegistrationsController#destroy executes more than 100 SQL queries
This controller executes more than 100 SQL queries, the maximum number of
queries allowed as per MR
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/16466. The number of
queries should be reduced to less than 100 and the corresponding allowlisted
sections of code (`Gitlab::QueryLimiting.disable!('...')` or `disable_query_limiting`) should be removed.
