 [https://mu.trac.wordpress.org/browser/trunk/wpmu-settings.php?rev=1422
 mu:1422] moved a check for single network vs multi-network into
 `wpmu_current_site()`. Existing code inside `wpmu_current_site()` intended
 for a `$sites` count of 1 become inaccessible.

 In [12921], the remaining count checks were consolidated into one, but the
 instance of `1 == count( $sites )` in that scenario is still not
 accessible.

 This doesn't hurt anything and the likelihood of this part of the function
 being reached is so extremely low. It does cause a double take. And made
 me investigate it.
