Use gitlab-default_value_with Rails 5

This forks live at https://github.com/gitlabhq/default_value_for/tree/69-fix-action_controller-parameters-handling
and fixes an issue where default_value_for wouldn't handle
`ActionController::Parameters` correctly with Rails 5.

This fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/54093.
