 In a WordPress Network, Add Site creates each new Site with the Current
 Theme set to Twenty Fifteen, even when that Theme has been deleted (long
 before the Add Site was performed).

 WSOD is displayed when viewing any "Front End" (non-Admin panel) URL, and
 no error messages are displayed, even with WP_DEBUG set to TRUE.

 The solution is immediately obvious on the Appearance-Themes panel where
 'ERROR: The theme directory "twentyfifteen" does not exist.' is displayed.
 Unfortunately, knowing to look there is not intuitively obvious.
