i18n Japanese date format cannot be filtered

[CHEN-WEI-YU]

Describe the bug
It seems that i18n use the long format, which is "%Y年%m月%d日(%a)", to show in the table list. When filtering, it deliver by this format and cannot search from database

  config.model "model_name" do
    configure :date_field_name do
      strftime_format "%Y-%m-%d"
    end
  end

I do this to let filter work, but it will display the column in this format too.

Reproduction steps
Use datepicker to pick a date on date field to filter, but not working.

Expected behavior
Show the list date field column in i18n long format, but deliver by iso8601 when filtering will be better.
