se-secondary-email-none not being used as default value for secondary email on email sub-section of settings

[bcolsson]

Description

There is an ftl string to localize "None" for the secondary email when no secondary email is set. The string is se-secondary-email-none. However, this string is not being used. Instead it appears row-defaults-status is being used. For certain gendered languages, like French, causing the incorrect form of the word to appear (e.g. Aucun instead of the correct Aucune).

Steps to reproduce

1. Set your preferred website language to French
2. Open the settings page to an account without a secondary email set
3. Observe Aucun (string: row-defaults-status) appearing instead of Aucune (string: se-secondary-email-none)

Expected result

The correct se-secondary-email-none is displayed.

Actual result

row-defaults-status is displayed.

Environment

Tested against production and storybook (https://storage.googleapis.com/mozilla-storybooks-fxa/commits/latest/fxa-settings/index.html?path=/story/components-settings-unitrowsecondaryemail--no-secondary-email)
