Network - VPN - 500 error on page load if VPN server was deleted or is under construction

[osbornm]

steps:

1. delete a VPN server from an account or mark it as under construction
2. load Network-->VPN

expected - page loads and indicates there is no VPN server actual - 500 error

NOTE - not sure if the server must be deleted, or deleted and marked as under construction or some other combo

Brent Heinz (1/18/2013) : Note: This happens because T3 Admins marked these disabled in the system (so they dont' show up anymore) and the hardware was actually deleted. Darren knows about this if you have questions. We just need to make sure we don't show yellow screen of death on this page.
