[FIX] web: correctly display nocontent helper if create='0'

When the root node of the arch has attribute 'create' set to '0',
the generated DOM element must have classname 'o_cannot_create'.
This is used to correctly display the nocontent helper (when there
is no record).

Before this rev., the helper indicated that the user can click on
'Create' to create a new record, even if the create action was
disabled. This was for example the case in Point of Sale > Orders.
