[FIX] web: add help tooltip from form view on fields

The help defined on a field via Studio is only visible when debug mode
is enabled

Steps to reproduce:
1. Install Contacts and Studio
2. Go to Contacts, open a contact and toggle Studio
3. Add a field in the form view and add a message in the Help Tooltip of
   the field
4. Close Studio
5. Without debug mode, the small question mark is not displayed next to
   the field so we cannot see the help tooltip

Solution:
First use the help defined on the field in the view, then the help
defined on the field in the model

Problem:
The tooltip help can also come from the view
