Fix issue with delete project container text

This MR fixes the behavior where the container text contained blank
restore until date for:
  * instances where delayed deletion is not enabled and days are set
 to zero.
  * instances that have enabled the delayed deletion but the group has
opted out of this feature.

Changelog: fixed
