Purge stale NetworkExtension/keychain data (#728)

- [x] NE managers were not deleted when unable to be decoded to a
profile
- [x] Keychain items were not deleted on profile removal
- [x] Perform clean-up on app launch
- [x] Perform clean-up on app active

Prematurely merged as #727 then reverted, this is the complete PR.
