Ensure rake tasks that don't need a DB connection can be run without one
When using ActiveRecord::Base.connection.active? without a DB connection, we get a "PG::ConnectionBad: could not connect to server" error because ActiveRecord::Base.connection doesn't exist. By using ActiveRecord::Base.connected? we ensure we don't get this error if the connection is missing, which is the all point of the Gitlab::CurrentSettings#connect_to_db? method!
