How to replicate:
- Create a shared template with some config in it, save
- Hit the preview button
Expected result: the preview is shown.
Actual result: an error shows up instead.

The preview of a shared VPN-client template seems to be failing with {'name': ['This field cannot be blank.'], 'vpn': ['A VPN must be selected when template type is "VPN"']}.
