Multisite - Number of sites and users still shows after sites are deleted.

[PILOTUSA123]

Bug:
Using a Multisites install when you execute /wp-admin/network/ and get to the screen that shows the number of sites and users in the network,for example if you have 5 sites and 5 users in the network and you delete 4 of sites and its users the system still shows that the network still have 5 sites, even with the fact they been deleted.

Corrective action:
Show the number of sites and users that are in the network and not show the ones that have been deleted.
