Swipe to delete. Address a couple things on iPad though:
1. Also check provider availability before showing view
fatalError hit on iPad when navigating from a ready provider
profile to a non-ready one. Similar to when navigating between
different VPN protocols.
2. Suppress assertion on deleted profile
Deleting current profile via swipe seems to re-render a new
NavigationLink with the deleted profile, which results in
loading a deleted profile and hitting the assertion. Not sure if
this is a programming error or a glitch in ForEach.
